<div>
<%= form.label :author, style: "display: block" %>
<%= form.text_field :author %>
</div>
<div>
<%= form.submit %>
</div>
<% end %>
This code is form.html.erb file where I added the rich_text_area in the box of content.
The issue faced was in the web application, after I am done writing the content in the text area,
it is not easy to reach any other element of the page to add more text.

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
First, I have a model called Answers for my trivia game. It stores the multiple possible answers there are to each trivia question (a quiz has_many answers). I created a form via scaffold to make an easy UI for submitting a question with a set of four answers.
I want to do this from one form. When the user currently hits submit, I can post all four answers -- each with a different answer_id but sharing the same question_id (so I can associate 4 answers with one question) -- successfully, like so:
<%= form_for(#question) do |f| %>
<% if #question.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#question.errors.count, "error") %> prohibited this question from being saved:</h2>
<ul>
<% #question.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="form-group">
<div class="field">
<%= f.label :question_text %><br>
<%= f.text_field :question_text, class: "form-control" %>
</div>
</div>
<div class="form-group">
<div class="field">
<%= f.label :category_id %><br>
<%= f.number_field :category_id, class: "form-control" %>
</div>
</div>
<h2>Answer Options</h2>
<%= f.fields_for :answers do |answer| %>
<div class="form-group">
<div class="answers">
<div class="field">
<%= answer.label :answer_1 %><br>
<%= answer.text_field :answer_text, class: "form-control" %>
</div>
</div>
</div>
<% end %>
<%= f.fields_for :answers do |answer| %>
<div class="form-group">
<div class="answers">
<div class="field">
<%= answer.label :answer_2 %><br>
<%= answer.text_field :answer_text, class: "form-control" %>
</div>
</div>
</div>
<% end %>
<%= f.fields_for :answers do |answer| %>
<div class="form-group">
<div class="answers">
<div class="field">
<%= answer.label :answer_3 %><br>
<%= answer.text_field :answer_text, class: "form-control" %>
</div>
</div>
</div>
<% end %>
<%= f.fields_for :answers do |answer| %>
<div class="form-group">
<div class="answers">
<div class="field">
<%= answer.label :answer_4 %><br>
<%= answer.text_field :answer_text, class: "form-control" %>
</div>
</div>
</div>
<% end %>
If I check in console, it works! I have four different answers (so they are four rows in the table but with the same question_id. What is weird is if I then use the edit route, instead of populating four inputs (like new does), it shows 16 text_field inputs for Answers (labeled Answer 1, Answer 2, Answer 3, Answer 4, Answer 1).
Finally, the other reason I think there could be an issue would be how I am updating the nested Answers attribute through the controller, like so:
def question_params
params.require(:question).permit(:question_text, :category_id, :correct_answer, :answers_attributes => [:id, :answer_text])
end
Am I setting this up incorrectly, such that it would iterate 4x when showing in the Edit file?
I think you need to do little different while rendering the form for edit action:
You can try something like this:
<%= form_for(#question) do |f| %>
<% if #question.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#question.errors.count, "error") %> prohibited this question from being saved:</h2>
<ul>
<% #question.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="form-group">
<div class="field">
<%= f.label :title %><br>
<%= f.text_field :title, class: "form-control" %>
</div>
</div>
<% unless #question.new_record? %>
<% #question.answers.each_with_index do |ans,i| %>
<%= f.fields_for :answers, ans do |answer| %>
<%= answer.label "answer_#{i+1}" %><br>
<%= answer.text_field :answer_text, class: "form-control" %>
<% end %>
<% end %>
<% else %>
<h2>Answer Options</h2>
<%= f.fields_for :answers, Answer.new do |answer| %>
<%= answer.label :answer_1 %><br>
<%= answer.text_field :answer_text, class: "form-control" %>
<% end %>
<%= f.fields_for :answers,Answer.new do |answer| %>
<%= answer.label :answer_2 %><br>
<%= answer.text_field :answer_text, class: "form-control" %>
<% end %>
<%= f.fields_for :answers,Answer.new do |answer| %>
<%= answer.label :answer_3 %><br>
<%= answer.text_field :answer_text, class: "form-control" %>
<% end %>
<%= f.fields_for :answers,Answer.new do |answer| %>
<%= answer.label :answer_4 %><br>
<%= answer.text_field :answer_text, class: "form-control" %>
<% end %>
<% end %>
<%= f.submit #question.new_record? ? "Add" : "Update" %>
<% end %>
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 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 }
