I have create an rails application with mongoid but im facing one problem at DATE
I created an scaffold with a name "posting"
When im editing date it will updated....
I follow the instruction of Railscast #238 Mongoid here
there is my posting.rb file
class Posting
include Mongoid::Document
field :title
field :description
field :comments
field :published, :type => Date
end
this my _from.html.erb
<%= form_for(#posting) do |f| %>
<% if #posting.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#posting.errors.count, "error") %> prohibited this posting from being saved:</h2>
<ul>
<% #posting.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :title %><br>
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :description %><br>
<%= f.text_field :description %>
</div>
<div class="field">
<%= f.label :published %><br>
<%= f.date_select :published %>
</div>
<div class="field">
<%= f.label :comments %><br>
<%= f.text_area :comments %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
and finally my show.html.erb file
<p id="notice"><%= notice %></p>
<p>
<strong>Title:</strong>
<%= #posting.title %>
</p>
<p>
<strong>Description:</strong>
<%= #posting.description %>
</p>
<p>
<strong>published:</strong>
<%= #posting.published %>
</p>
<p>
<strong>Comments:</strong>
<%= #posting.comments %>
</p>
<%= link_to 'Edit', edit_posting_path(#posting) %> |
<%= link_to 'Back', postings_path %>
What do you mean by not working? doesn't look like you have used published property in any of your views.
in your show.html.erb you are using
<%= f.date_select :pub %>
and in your show.html.erb you are using
<%= #posting.pub %>
However there is no property called pub in your Posting model. What you have there is called published
field :published, :type => Date
You either need to rename it in the model, or in the views to match.

I'm learning Rails and I try to use scaffold to generate some code.
Everything seems to be OK after this except I miss an input in one of my forms and I don't know why.
Someone could explain this ?
Here the partial form which generates the view:
_form.html.erb
<%= form_with(model: advertisement, local: true) do |form| %>
<% if advertisement.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(advertisement.errors.count, "error") %> prohibited this advertisement from being saved:</h2>
<ul>
<% advertisement.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= form.label :title %>
<%= form.text_field :title %>
</div>
<div class="field">
<%= form.label :content %>
<%= form.text_area :content %>
</div>
<div class="field">
<%= form.label :price %>
<%= form.number_field :price %>
</div>
<div class="field">
<%= form.label :state %>
<%= form.text_field :state %>
</div>
<div class="field">
<%= form.label :user_id %>
<%= form.number_field :user_id %>
</div>
<div class="actions">
<%= form.submit %>
</div>
<% end %>
The HTML output for this input:
<div class="field">
<label for="advertisement_title">Title</label>
<input type="text" name="advertisement[title]" id="advertisement_title" />
</div>
Thank you everyone
OK I got it!
It's because of the Adblock extension.
On every page where it is enabled, it injects CSS directly into the page and adds a
display: none !important;
for hundreds of defined id's.
Unfortunately for me, #advertisement_title is one of them!
It works when I desactivate it
adblock display none
I'm working on an app where i nested the 3 model
resources :genres do
resources :stories do
resources :episodes
end
end
Meanwhile, i've been able to write the form for genres and stories as in
<%= form_for(genre) do |f| %>
<% if genre.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(genre.errors.count, "error") %> prohibited this genre from being saved:</h2>
<ul>
<% genre.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<div class="field">
<%= f.label :name %>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :description %>
<%= f.text_area :description %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
and stories
<%= form_for([#genre, #genre.stories.build]) do |f| %>
<div class="field">
<%= f.label :title %>
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :summary %>
<%= f.text_area :summary %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Can someone pls tell me how to write the form for episodes...
When i wrote this
<%= form_for([#genre.stories, #genre.#stories.episodes.build]) do |f| %>
<div class="field">
<%= f.label :title %>
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :content %>
<%= f.text_area :content %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
I got this error
syntax error, unexpected tIVAR, expecting '(' ...#genre.stories, #genre.#stories.episodes.build]) do |f| #out... ... ^ C:/Users/Adegbite/Documents/Apps/twiliste2/app/views/episodes/_form.html.erb:1: syntax error, unexpected ']', expecting keyword_end ...#genre.#stories.episodes.build]) do |f| #output_buffer.safe_... ... ^ C:/Users/Adegbite/Documents/Apps/twiliste2/app/views/episodes/_form.html.erb:16: syntax error, unexpected keyword_ensure, expecting end-of-input
Thanks.
This:
<%= form_for([#genre.stories, #genre.#stories.episodes.build]) do |f| %>
Should be more like:
<%= form_for([#genre, #story, #story.episodes.build]) do |f| %>
Of course, you'll have to set #genre and #story appropriately in the new action of your EpisodesController.
BTW, #genre.#stories makes no sense and is not valid. #stories is an instance variable which, presumably, contains (or would contain) one or more stories. .stories is a method call on an instance of Genre. .#stories is nothing.
I'm building rails application and I use form_for to render the form. Everything works fine works fine except one text field has ActiveRecord_Associations_CollectionProxy inside the text which I'm not sure where it's coming from.
Here's my form
<%= form_for(#video, html: { class: "directUpload" }, multipart: true) do |f| %>
<% if #video.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#video.errors.count, "error") %> prohibited this user from being saved:</h2>
<ul>
<% #video.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :title %><br>
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :path %><br>
<%= f.file_field :path%>
</div>
<div class="field">
<%= f.label :tags %><br>
<%= f.text_field :tags %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
And here's my Video model
class Video < ActiveRecord::Base
belongs_to :user
has_many :video_tags
has_many :tags, through: :video_tags
end
Here's the screenshot
You have multiple tags that you want show in form. Your controller could serve all tags for form where you could show them with http://apidock.com/rails/ActionView/Helpers/FormOptionsHelper/options_from_collection_for_select for example.
I have the following form
<%= form_for(#user) do |f| %>
<% if #user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#user.errors.count, "error") %> prohibited this user from being saved:</h2>
<ul>
<% #user.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<%= #user.errors.messages[:name] %>
<div class="field">
<%= f.label :name %><br>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :email %><br>
<%= f.text_field :email %>
</div>
<div class="field">
<%= f.label :password %><br>
<%= f.password_field :password %>
</div>
<div class="field">
<%= f.label :phone %><br>
<%= f.text_field :phone %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
I want to display form error for each field below it instead of everything on the top. Went through rails guide but was not able to figure how to do it.
You can write a helper to return error message for any field of any object
In /app/helpers/application_helper.rb:
def show_errors(object, field_name)
if object.errors.any?
if !object.errors.messages[field_name].blank?
object.errors.messages[field_name].join(", ")
end
end
end
In view file:
<div class="field">
<%= f.label :name %><br>
<%= f.text_field :name %>
<p class='error'><%= show_errors(#user, :name) %></p>
</div>
I know you are usually supposed to use the linking between new/create and edit/update in rails, but I have a case where I need something else. Is there anyway I can achieve this same connection?
I have a form for a model and I want it to post the data (similar to how a new view, post to the create action).
Here is my form
<div id="new-job">
<%= form_for(#job) do |f| %>
<% if #job.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#job.errors.count, "error") %> prohibited this job from being saved:</h2>
<ul>
<% #job.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :location %><br />
<%= f.text_field :location %>
</div>
<div class="field">
<%= f.label :description %><br />
<%= f.text_area :description %>
</div>
<div class="actions">
<%= f.submit "create job", id: "submit-job", class: "button small radius" %>
<%= link_to "go back", jobs_path, class: "button small radius secondary" %>
<div id="new-job-errors"> </div>
</div>
<% end %>
</div>
Use the :url option.
= form_for #job, :url => company_path, :html => { :method => :post/:put }
