Trying to use Twitter gem for rails 4 to let users search twitter for tweets containing a keyword. I've done my best to following the instructions in the API, but am obviously getting something wrong.
My Questions controller is returning the following error: Twitter::Error::BadRequest at /questions.
"Query parameters are missing"
I have a Twitter initialiser with all the oauth and app key/secret.
Here's my controller code:
class QuestionsController < ApplicationController
require 'twitter'
def new
#question = Question.new
end
def create
#question = Question.new(question_params)
#question.return = Twitter.search(params[:search])
if #question.save
redirect_to question_path(#question)
end
end
def show
#question = Question.find(params[:id])
end
def index
#questions = Question.all
end
private
def question_params
params.require(:question).permit(:search)
end
end
And my views: new.html.erb
<%= simple_form_for #question do |f| %>
<%= f.input :search, :width => '100' %>
<%= f.button :submit %>
<% end %>
show.html.erb
<%= #question.id %></br>
<%= #question.search %></br>
<%= #question.return %></br>
<%= #question.created_at %></br>
index.html.erb
<% #questions.each do |q| %>
<%= q.search %>
<%= q.return %>
<% end %>
Any thoughts? Thanks in advance!
As far as I'm aware the only parameter that the Twitter API requires for doing a search is the query itself, as in, a string. See https://dev.twitter.com/docs/using-search if you haven't already.
Are you maybe submitting the form with no query?

I have a standard create method in the controller responsible for creating a new Transaction record. The Transaction record has a mandatory transaction_type field which I hide in the view and automatically assigning it a value by passing it a params[:filter] so I have one _form for both withdrawal and deposit transactions, like below:
#index.html.erb
<%= link_to 'Add funds', new_transaction_path(filter: 'deposit') %>
<%= link_to 'Withdraw Funds', new_transaction_path(filter: 'withdrawal') %>
#new.html.erb
<%= render 'form', transaction: #transaction, transaction_type: params[:filter] %>
#_form.html.erb
<%= simple_form_for #transaction do |f| %>
<%= f.error_notification %>
<%= f.error_notification message: f.object.errors[:base].to_sentence if f.object.errors[:base].present? %>
<%= f.text_field :transaction_type, value: transaction_type, type: "hidden" %>
<%= f.input :amount, placeholder: 'Amount', label: false %>
<%= f.button :submit, 'Submit' %>
<% end %>
If for some reason the validation fails, to properly display the errors, the :new view will be rendered. Unfortunately, in this case, if the user fills out the entire form again (after first failed), the record will not be created because params[:filter] was not passed. Is there any way to pass original params[:filter] directly to the view?
#controller
# POST /transactions
def create
#transaction = wallet.transactions.new(transaction_params)
if #transaction.save
redirect_to :index, notice: 'Transaction was successfully created.'
else
render :new
end
end
While I understand the aspect of reusing the view code you really should consider creating separate routes and controllers and solving the code duplication issues by using inheritance and locals instead of by sneaking along a hidden parameter.
resources :deposits, :withdrawls, only: [:new, :create]
class TransactionsController < ApplicationController
helper_method :create_transaction_path
def new
#transaction = Transaction.new
render 'transactions/new'
end
def create
#transaction = Transaction.new(transaction_params) do |t|
t.transaction_type = transaction_type
end
if #transaction.save
yield #transaction if block_given?
success_response
else
yield #transaction if block_given?
failure_response
end
end
private
def transaction_type
controller_name.singularize
end
def create_transaction_path
polymorphic_path(controller_name)
end
def transaction_params
params.require(:transaction)
.permit(:foo, :bar, :baz)
end
def success_response
redirect_to transactions_path,
notice: 'Transaction was successfully created.'
end
def failure_response
render 'transactions/new'
end
end
class DepositsController < TransactionsController
# POST /deposits
def create
super do |transaction|
# do something just when making a deposit
end
end
end
class WithdrawlsController < TransactionsController
# POST /withdrawls
def create
super do |transaction|
# do something just when making a withdrawl
end
end
end
# app/views/transactions/_form.html.erb
<%= simple_form_for transaction, url: create_transaction_path do |f| %>
<%= f.error_notification %>
<%= f.error_notification message: f.object.errors[:base].to_sentence if f.object.errors[:base].present? %>
<%= f.input :amount %> # Do not use placeholders instead of labels
<%= f.button :submit, 'Submit' %>
<% end %>
<%= link_to 'Add funds', new_deposit_path %>
<%= link_to 'Withdraw Funds', new_withdrawl_path %>
Why?
Because it gives you endpoints that do a single job and it also gives you the obvious structure for your code when the requirements diverge as they most certainly will.
Stashing the value as a hidden field in the form is the right idea, but you're using two different parameter names for the same thing.
Your link_to call passes the transaction type as filter:
<%= link_to 'Add funds', new_transaction_path(filter: 'deposit') %>
In your form, you are putting it in a hidden field called :transaction_type. Thus, when the form submits the value now goes to your controller in params[:transaction_type]. One simple fix is to change the name of your hidden field:
<%= hidden_field_tag :filter, params[:filter] %>
at the moment I am attempting to create a form for my website that will allow for users to input information and then the information with be POST'ed to my database for storage. I am a new ruby on rails developer so keep that in mind.
I was able to get to the point where the user could see the form and type in information but once they hit the submit button I recieve an error, and that error is
ArgumentError in StudentsController#create
wrong number of arguments (0 for 1) in app/controllers/students_controller.rb:13:in `create'
The parameters that were sent were the following
{"utf8"=>"✓",
"authenticity_token"=>"bLalQ9Ek5ziaGiGHj03AGPCTIABAgcT+o4eTgN44qv44dxNDlrGA0h2u5BSTQVTMh+YgA/mLPQee05lT7mxCsw==",
"student"=>{"first_name"=>"Andrew",
"last_name"=>"Terra"},
"commit"=>"Submit"}
Below is my students_controller.rb file.
class StudentsController < ApplicationController
def index
#students = Student.all
end
def new
#student = Student.new
end
def create
#student = Student.new(params.require[:student])
if #student.save
redirect_to students_path
end
end
def destroy
#student = Student.find_by_id(params[:id])
if #student.destroy
redirect_to students_path
end
end
end
Below is my views/students/_form.html.erb file
<%= form_for #student do |f| %>
<p>
<%= f.label :first_name %>
<%= f.text_field :first_name %>
</p>
<p>
<%= f.label :last_name %>
<%= f.text_field :last_name %>
</p>
<%= f.submit "Submit" %>
<% end %>
Below is my /views/students/index.html.erb file
<%= link_to "Create new information", new_student_path %> <br /> <hr>
<% #students.each do |fo| %>
Firstname: <%= fo.first_name %> <br />
Lastname: <%= fo.last_name %> <br />
<%= link_to "Delete info?", student_path(student), :data=>{:confirm=>"Are you sure ?"}, :method=> :delete %>
<br />
<hr>
<% end %>
Finally, here is my /views/students/new.html.erb file
Enter new info
<hr>
<%= render :partial => "form" %>
And I did remember to put resources :students in my routes file. I searched around and found other people who had previously had this problem but none of the solutions worked on the code that I have written. So I was wondering if anyone could point me in the direction of where the bug is and how exactly I can fix it. Thank you.
You need to add a new private method:
private
def student_params
params.require(:student).permit(:first_name, :last_name)
end
And then as said before change your create method to:
def create
#student = Student.new(student_params)
if #student.save
redirect_to students_path
end
end
I recommend reading the documentation on Strong Parameters - to better understand how they work. https://github.com/rails/strong_parameters
You have to change
params.require[:students] to params.require(:students)
But this is still not good way to handle your params for create action, you should add private method student_params to your controller where you would whitelist your params. Like this:
def student_params
params.require(:student).permit(:first_name, :last_name)
end

I am very new to rails.. I want to update the data which matches my condition.. I have a form which submits two values(order_no, order_date)., and i want to retrieve all the data which relates to that order_no.. I dont know to write the controller code for this . Can someone help me.. here is my code.. I am really sorry if you feel this doubt is silly. I really dont know how to code efficiently in rails.
//my view
<%= form_for([#order], :url=>{:controller=>"users"}) do |i|%>
<tr><td><%= i.label :order_no,"Order No" %></td></tr>
<tr><td><%= i.text_field :order_no %></td></tr>
<tr><td><%= i.label :order_date,"Order Date" %></td></tr>
<tr><td><%= i.text_field :order_date %></td></tr>
<%= link_to "Update",users_update_orderSummary_path(i) %>
<% end %>
my controller,
def edit_order
#order=Order.find params[:id]
end
def update_order
#order=Order.find params[:id]
#order=Order.where(order_no = params[:order_no])
if #order.update_attributes(order_params)
flash[:success] = "Order updated"
redirect_to :action=>"login"
else
render "edit_order"
end
end
And I am getting the following error..
ActiveRecord::RecordNotFound in UsersController#update_orderSummary
Couldn't find Order with 'id'=
Kindly please help me..
You should put your order actions into a separate controller:
#config/routes.rb
resources :orders, only: [:edit, :update], module: :users #-> url.com/orders/:id/edit
#app/controllers/users/orders_controller.rb
class Users::OrdersController < ApplicationController
def edit
#order = Order.find params[:id]
end
def update
#order = Order.find params[:id]
#orders = Order.where order_no: params[:order][:order_no]
if #orders.update_all order_params
redirect_to action: :logic, success: "Order Updated"
end
end
private
def order_params
params.require(:order).permit(:order_no, :order_date)
end
end
#app/views/users/orders/new.html.erb
<%= form_for #order do |f| %>
<%= f.text_field :order_no %>
<%= f.text_field :order_date %>
<%= f.submit %>
<% end %>
Your main problem is that you're trying to do two things with the update method -- Order.find && Order.where.
You can't update both - you have to do one.
I have used update_all, which can be used on your Order.where collection; if you wanted to update a single object, just use #order.update
I'm using rails 4.0.8. I added a comment section to a model called 'Things', but I keep getting the same error "param is missing or the value is empty: thing" when I press the submit comment button. It says the error is in the Things#Controller. What am I doing wrong?
UPDATE: I removed the url path from the form, but a new error returns "Couldn't find Thing without an ID". The error is in Comments#Controller.
VIEW FOR THING/SHOW
<div id= "thing">
<h1>
<%= #thing.name %>
</h1>
<br>
<div id= "commentsection">
Comments
<div id= "comments">
<br>
<% #thing.comments.each do |c| %>
<%= c.username %>
<br>
<%= c.text %>
<% end %>
<%= form_for #comment, :url => thing_path do |f| %>
<%= f.label :username %>
<%= f.text_field :username %>
<%= f.label :comment %>
<%= f.text_field :text %>
<%= f.submit "Enter", class: "btn btn-small btn-primary" %>
<% end %>
</div>
</div>
</div>
THINGS CONTROLLER
class ThingsController < ApplicationController
def show
#thing = Thing.find(params[:id])
#thing.comments.build
#comment = Comment.new
end
def index
end
def new
#thing = Thing.new
#things = Thing.all
end
def create
#thing = Thing.new(thing_params)
if #thing.save
redirect_to #thing
else
render 'new'
end
end
private
def thing_params
params.require(:thing).permit(:name, :avatar)
end
end
COMMENTS CONTROLLER (I put asterisks around the line where the error is)
class CommentsController < ApplicationController
def show
#comment = Comment.find(params[:id])
end
def new
#comment = Comment.new
#comments = Comment.all
end
def create
****#thing = Thing.find(params[:thing_id])****
#comment = #thing.comments.create(comment_params)
redirect_to thing_path(#thing)
end
end
private
def comment_params
params.require(:comment).permit(:user, :text, :upvotes, :downvotes, :thing_id)
end
end
ROUTES
Website::Application.routes.draw do
get "comments/new"
get "comments/show"
get "things/new"
root 'home_page#home'
get "all/things/new" => 'things#new'
get "all/allthings"
resources :things
resources :good_comments
get "things/show"
get "things/results"
end
You are posting the #comment form to post '/things' path.
<%= form_for #comment, :url => thing_path do |f| %>
It should just be <%= form_for #comment do %> (Rails is smart enough to plug in the comments_path) or if you feel like being more explicit (even though it's not necessary)
<%= form_for #comment, url: :comments_path do %>
Another note though, if you want that Comment to be tied to that specific Thing then in your models it should be
Class Thing
has_many :comments
end
Class Comment
belongs_to :thing
end
Then make sure in your database comment has a thing_id foreign_key field and then your form for comment should actually look like
<%= form_for #thing, #comment do %>
<% end %>
I am new to Rails and working on creating a generic "facebook" type of app as practice with users and posts associated with each user. However, I'm currently having an issue where I think the form that I am using to create the posts is also being rendered out as a blank post with no post ID where I display all of the posts in a section below. I think that this post is being shown even before it is being saved to the database.
Here is my code in my view:
<div class="newpostcontainer">
<div class="newposttext">
<%= form_for([#user, #user.posts.build]) do |f| %>
<%= f.text_area :post, size: "69x1" %>
</div>
<div class="newpostsubmitbutton">
<%= f.submit %>
</div>
<% end %>
</div>
<% #user.posts.reverse_each do |p| %>
<div class="postedcontainer">
<div class="minipostpic">
<%= image_tag #user.photo.url, width: 32, height: 32 %>
</div>
<div class="nameofposter"><%= #user.name %></div>
<div class="dateofpost"><%= p.created_at%></div>
<div class="postcontent"><%= p.id%></div> <br>
<div class="postcontent"><%= p.post%></div> <br>
<div class="likecommentdelete">
<%= link_to "Delete", [p.user, p], method: :delete %> | Like | Comment
</div>
</div>
<%end%>
</div>
Here is my controller:
def index
#user = User.find(params[:user_id])
#posts = #user.posts.all
end
def create
#user = User.find(params[:user_id])
#post = #user.posts.create!(post_params)
redirect_to user_path(#user)
end
def show
#user = User.find(params[:user_id])
#post = #user.posts.find(params[:id])
redirect_to user_path(#user)
end
def destroy
#user = User.find(params[:user_id])
#post = #user.posts.find(params[:id])
#post.destroy
if #post.destroy
redirect_to user_path(#user)
else
redirect_to users_path
end
end
private
def post_params
params.require(:post).permit!
end
end
And here is my model:
class Post < ActiveRecord::Base
belongs_to :user
has_many :comments
validates_presence_of :post
end
I'm pretty sure the issue has something to do with my form to create the new post because when I remove it or comment it out, the extra blank post with no post ID goes away.
Any thoughts or suggestions?
Thank you!!
I think you need to permit the field values to be posted:
i.e.,
params.require(:post).permit!
should be
params.require(:post).permit(:name, :post)
then only it will POST I think.
Hope it helps :)
This is because of rails 4 strong parameter feature. You need to whitelist your active models parameters. For more details refer to here.
In your case you need to do something like this:
params.require(:post).permit(:post)
where the ":post" inside require is your model and the other one is your permitted field that is your textarea.
Several issues -
Form
<%= form_for([#user, #user.posts.build]) do |f| %>
Why are you building an associative object? #user.posts.build will not persist your data, and will cause all sorts of non-conventional issues I would highly recommending building the posts associative object in your controller's new action before using in the view, so you can do this:
#app/controllers/users_controller.rb
def new
#user = current_user
#user.posts.build
end
<%= form_for #user do |f| %>
Association
You're trying to edit the post attribute with this statement:
<%= f.text_area :post, size: "69x1" %>
This won't work in any circumstance, as :post is an association, not an object. Rails only allows you to change / add attributes to specific objects, which means you'll be better doing something like this:
<%= f.fields_for :posts do |p| %>
<%= p.text_area :title %>
<%= p.text_area :body %>
<% end %>
Strong Params
You're currently permitting all your params? You'll be better doing this:
def post_params
params.require(:user).permit(posts_attributes: [:title, :body])
end
Use Posts Controller
A better way will be to just use the posts_controller, like this:
#app/controllers/posts_controller.rb
def new
#post = Post.new
end
def create
#post = Post.new(post_params)
#post.save
end
#app/views/posts/new.html.erb
<%= form_for #post do |f| %>
<%= f.text_field :title %>
<%= f.text_field :body %>
<% end %>
