Rails routing params mismatch error in rails - ruby-on-rails

I am adding excel import feature but I am getting error. :id params is getting passed instead of :project_id params.
Below is my code-
index.html.erb
<%= form_tag import_project_stages_path ,multipart: true do %>
<%= file_field_tag :file %>
<%= submit_tag "Import" %>
<%end %>
stage_controller.rb
def import
Stage.import(params[:file])
redirect_to root_url, notice:"Projects imported. "
end
routes.rb
resources :projects do
resources :stages do
collection {post :import}
end
end
error
No route matches {:action=>"import", :controller=>"stages", :id=>"1"},
missing required keys: [:project_id]

Your nested resources will produce a route path that looks like <host>/projects/:project_id/stages. So, you need to include the parent project ID as part of the path in your form_tag. You can do that by including the project as a parameter to the URL helper method:
<%= form_tag import_project_stages_path(#project), multipart: true do %>
...
<%end %>

Update attributes rails - No route matches [POST]

I'm trying to basically update my integration object attribute "filters". I have a integrations controller and what seems the proper actions to do so. But when I try to save after filling out the text-field I get this error No route matches [POST], I understand what it's saying but isn't update a post? Here is my code for clarity.
Controller
def update
#integrations = current_account.integrations.find(params[:id])
attrs = params.require(:integration).permit(:filters)
if #integrations.update_attributes(attrs)
redirect_to account_integration_path
else
render :filters
end
end
def filters
#integrations = current_account.integrations.find(params[:id])
end
View
<%= form_for #integrations, url: filters_account_integration_path do |f| %>
<%= f.text_field :filters, class: "tag-autocomplete" %>
<%= link_to "Save", account_integration_path, method: :post, class: [ "button", "button--modal" ] %>
<% end %>
Routes
resources :integrations, only: [ :index, :destroy, :update ] do
get "filters", on: :member
end
Hopefully that is enough info let me know if you need more? My basic question is why is this not updating the integration object? Isn't update a post?
resources generates seven routes by default. You're using it to generate only three of those. Those three routes will look like this:
GET /integrations
DELETE /integrations/:id
PATCH /integrations/:id/edit
Your form, on the other hand, is trying to use this route:
POST /integrations/:id
which doesn't match any of the generated routes.
Instead, try using the default form helpers:
<%= form_for #integrations, url: url_for(:controller => :integrations, :action => :update, :id => #integrations.id) do |f| %>
<%= f.text_field :filters, class: "tag-autocomplete" %>
<%= f.submit "Save" %>
<% end %>
That's assuming that #integrations is a single Integration resource. If it isn't, you have bigger problems than just this.

Send url param from form_tag Rails

this is my case:
I'm in /car
and I want to pass a car model through a form like:
/car/:model for example /car/bmw+z4
This is my form:
<%= form_tag(get_model_path, :method => 'get') do |f| %>
<%= f.text_field, :model %>
<% end %>
And an error message says:
No route matches {:action=>"get_model", :controller=>"cars"} missing required keys: [:model]
All this without model or activerecord, becouse is an API consumption.
Any idea?
Yes pass it :
<%= form_tag(get_model_path(model: 'name'), :method => 'get') do |f| %>
<%= f.text_field, :model %>
<% end %>
Here is what I reproduced and also fixed. Look the routes
$ rake routes | grep car
get_model GET /car/:model(.:format) notifications#get_model
Now look at the console:
2.2.1 :001 > app.get_model_path
ActionController::UrlGenerationError: No route matches {:action=>"get_model", :controller=>"notifications"} missing required keys: [:model]
2.2.1 :002 > app.get_model_path(model: "foo")
=> "/car/foo"
I have in my routes.rb file :
get 'car/:model', to: 'notifications#get_model', as: 'get_model'
most simple way to pass any value from form is to use hidden_fields.So in your form...
<%= form_tag(get_model_path, :method => 'get') do |f| %>
<%= f.text_field, :model %>
<% f.hidden_field(:hidden_value, :value=>"MyModelValue")%>
<% end %>
so at the controller,you can get the value using:-
##to get MyModelValue
model_value=params[:MODEL][:hidden_value]
BUT if you want to pass values visible in url while submitting form..then all all form values will get passed along with url which is not good when it comes to security.That's why every form should be submitted using POST and not GET.its your call :)

Routing a resource to controller

How do you route a resource to its controller? I am using the resource in an edit page for a different model, so my actions are being routed to its model controller first.
This edit page requests from
class Grandstreamers::ResellersController < ApplicationController
def new
end etc...
I am trying to route the requests to here instead:
Grandstreamers::CertificatesController < ApplicationController
def new
end
def update
end etc...
This is my form under views/grandstreamers/resellers/edit.html.erb
<%= form_for #untrained, :url => certificates_update_path(#untrained) do |f| %>
<p> Trained Users </p>
<%= select_tag "certificate[user_id]", options_for_select(#current_trained.collect{|x| [x.name, x.id]}), {:multiple => :multiple} %>
<%= f.submit "Un-Train", class: "btn btn-large btn-primary" %>
<% end %>
<%= form_for #trained, :url => certificates_create_path(#trained) do |f| %>
<p> Non-Trained Users </p>
<%= select_tag "certificate[user_id]", options_for_select(#non_trained.collect{|x| [x.name, x.id]}), {:multiple => :multiple} %>
<%= f.submit "Train", class: "btn btn-large btn-primary" %>
<% end %>
My route is:
resources :certificates
Note that the
:url => certificates_create_path
is not correct and not working. Is there a way to specify this route in my routes.rb file or in my form? Thank you
EDIT
This is my resellers_controller edit() which is routes to first.
#trained = Certificate.new(params[:certificate])
#Trying to get to certificates_controller update. Then update the :attend to "No"
##untrained = Certificate.new(params[:certificate])
##untrained = Certificate.find(params[:id])
##untrained = Certificate.find_by_user_id(params[:id])
#untrained is not defined, I am not sure how to get it to just go to my certificate controller. For #trained I can define it since its not made yet and does not give me errors when it cant find a correct value.
My certificates controller which uses create() but cannot get to update()
def create
#trained = Certificate.new(params[:certificate])
if #trained.save
#trained.update_attributes(attend: "Yes")
end
redirect_to grandstreamers_resellers_path
end
def update
#untrained = Certificate.find(params[:id])
#untrained.update_attributes(attend: "No")
redirect_to grandstreamers_resellers_path
end
Major Issue
The instance variable #trained and #untrained need to be defined somehow in reseller_controller. What can I define them as to load the edit page?
Part Solution
I defined this is in my resellers_controller and it loads the edit page now.
#untrained = User.find(params[:id])
Now I get this error:
No route matches [PUT] "/certificates.1"
I believe the problem is you need to let routing know the full name to the controller.
From the Rails routing guide:
scope module: 'Grandstreamers' do
resources :certificates
end
Use these paths when creating the form:
<%= form_for #untrained, :url => certificate_path(#untrained), :method => :put do |f| %>
<%= form_for #trained, :url => certificates_path, :method => :post do |f| %>
use this his routes.rb file
namespace :grandstreamers do
resources :certificates
end

How to fix undefined method error in rails?

I keep getting an error saying: undefined method `androids_path' for #<#:0x007ff5edcd5330>. It's saying the error is at line 1 in new.html.
The name of the model is Android and is at android.rb. Any advice on how to fix this?
In androidapps_controller.rb:
def new
#android = Android.new
end
In new.html I have:
<%= form_for(#android, validate:true) do |f| %>
<% #android.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
<p>
<%= f.label :title %><br />
<%= f.text_field :title %>
</p>
<%= f.submit %>
<% end %>
routes.rb
Grabapp::Application.routes.draw do
root :to => 'iosapps#index'
get "static_pages/home"
get "static_pages/add"
get "static_pages/about"
devise_for :users
resources :iosapps
resources :androidapps
Add to your routes.rb:
resources :android
You're error is because you've asked form_for to do resource based routing!
<%= form_for(#android, validate:true) do |f| %>
But you didn't define the resource based routing required to make it work!
Your model and controller are not matched (Android vs AndroidApp), so need to specify the correct url in your form:
<%= form_for(#android, validate: true, url: androidapps_path) do |f| %>
<%= form_for(#android, validate:true) do |f| %> automatically sets up the correct HTTP method (normally POST or PUT) with the HTML markup for a form. It also assumes you have a url set up called /androids in the case of POST and /androids/:id in the case of PUT. So for this to work you need to tell rails to create the necessary routings. This is done by adding the following line in config/routes.rb namely resources :androids.
This is why is is better to match up your model and controller names, Rails can then automatically infer the correct controller actions based on the model name.
You need to read up a bit more on routing and how it works. Do it here: http://guides.rubyonrails.org/routing.html

Rails 3 routing not generating proper paths for new vs edit views

I'm getting some funkiness that is absolutely confounding me with Rails 3. I can't seem to get the routing to generate the proper path using the (mostly) standard _form style of the scaffold.
First off, I'm doing everything within an "admin" namespace. I'm finding that the form partial throws a routing error if I use admin_team_path(#team) to generate the path when creating a new Team, but then submitting the form when editing, it throws an error unless I use admin_teams_path.
admin_team_path(#team) where #team = Team.new throws this error:
No route matches {:controller=>"admin/teams", :action=>"show", :id=>#}
Meanwhile...
admin_teams_path(#team) where #team = throws this error:
The action 'edit' could not be found for TeamsController
In the latter case, it seems to be directing to the URL: http://localhost:3000/teams/1/edit - it's not recognizing the namespace properly.
Here's my full _form.html:
<%= semantic_form_for(#team, :url => admin_teams_path(#team)) do |f| %>
<%= f.semantic_errors %>
<%= f.inputs do %>
<%= f.input :user_id %>
<%= f.input :league_id %>
<%= f.input :name %>
<% end %>
<%= f.buttons do %>
<%= f.commit_button :button_html =>{:class => "primary"} %>
<% end %>
<% end %>
What gives? What's the right way to create this form partial so it works for both new and edit actions?
Namespaces seem to be such a mess to work with.
Presuming you have defined your routes in a RESOURCEful manner, like so:
namespace :admin do
resources :teams
end
Then, in your _form partial you can let rails take care of the action like so:
<%= semantic_form_for(["admin", #team]) do |f| %>
.... #rest of the code
<% end %>
