I have an assessment form that renders a list of questions, and accepts answers for each question. The form data is submitted manually via ajax.
I'm having an issue when trying to pre-populate the data in my edit view. Here's how my views look:
edit.html.erb:
<div class="container">
<%= render 'assessment_form', :locals=> {:assessment => #assessment} %>
</div>
_assessment_form.html.erb:
<%= form_for #assessment do |f| %>
<%= f.submit 'Save', :class=> "btn btn-primary", :style=>"width: 100%;" %>
<div class="col-sm-2 col-sm-offset-10">
<h4>Show on Followup?</h4>
</div>
<% #assessment.questions.where(category:"S").each do |question| %>
<%= render 'question_fields', :question=> question, :f=> f %>
<% end %>
<%= f.hidden_field :patient_id, :value=> #assessment.patient.id %>
<%= f.hidden_field :template_id, :value=> #assessment.template_id %>
<% end %>
_question_fields.html.erb:
<p><%= question.content %></p>
<%= f.fields_for :answer do |builder| %>
<div class="row question">
<div class="col-sm-2 pull-right toggle">
<%= builder.check_box :tracking, {:checked=> false, :class=>"trackable", :data => {:'on-text' => "Yes", :'off-text' => "No", :'on-color'=> "success", :question => question.id}}, 0 , 1 %>
</div>
<div class="col-sm-10">
<%= builder.text_area :content, :class=>"form-control question-field", :data => {:question => question.id} %>
</div>
</div>
<% end %>
But none of the answers content are rendering in the view, the form fields are blank.
Here's an example call: Assessment.last.answers.first.content will give me the string "test". That should be showing up in my text_area box but it's not.
Just do, the instance variable #assessment is passed to the partial.
<%= render 'assessment_form' %>

<%= form_tag("/posts/create") do %>
<div class="form">
<div class="form-body">
<% #post.errors.full_messages.each do |message| %>
<div class="form-error">
<%= message %>
</div>
<% end %>
<div class="continent">
<label>continent<br>
<%= #post.continent %>
<%= select :continent,
[["Africa","AF"],["North America","NA"],["Oceania","OC"],["Asia","AS"],["Europe","EU"],["South America","SA"]],
:prompt => "Select" %>
</label>
</div>
<div class="country">
<label>country<br>
<%= #post.country %>
<%= select :country,
[["Japan","JP"],["China","CH"]],
:prompt => "Select" %>
</label>
</div>
<div class="title">
<label>title<br>
<textarea name="title"><%= #post.title %></textarea>
</label>
</div>
<input type="submit" value="POST">
</div>
</div>
<% end %>
I want to set a select tag for choosing user's continent and country in the form
But It doesn't work well
I've tried some way to solve this problem.
And I just got the shape which is like "Select tag" but it's only included "prompt"
Please give me some advice.
FormOptionsHelper`s select takes these args
select(object, method, choices = nil, options = {}, html_options = {}, &block)
Try explicit putting options like this:
select :post, :country, [["Japan","JP"],["China","CH"]], { :prompt => "Select" }, { other_html_options }
If you are in a form context make this
<%= form_tag("/posts/create") do |form| %>
<%= form.select :country, [["Japan","JP"],["China","CH"]], { :prompt => "Select" }, { other_html_options } %>
<% end %>
First start off by creating the correct routes:
resources :posts
In Rails you create a resource by sending a POST request to the collection path ('/posts').
Then create the form with form_for(#post) or form_with(model: #post) (Rails 5.1+) and bind the model instance to the form builder.
<%= form_for(#post) do |f| %>
<div class="form">
<div class="form-body">
<% f.object.errors.full_messages.each do |message| %>
<div class="form-error">
<%= message %>
</div>
<% end %>
<div class="continent">
<%= f.label :continent do %>
<%= f.select :continent,
[["Africa","AF"],["North America","NA"],["Oceania","OC"],["Asia","AS"],["Europe","EU"],["South America","SA"]],
prompt: "Select" %>
<% end %>
</div>
<div class="country">
<%= f.label :country do %>
<%= f.select :country,
[["Japan","JP"],["China","CH"]],
:prompt => "Select" %>
<% end %>
</div>
<div class="title">
<%= f.label :title do %>
<%= f.text_area_field :title %>
</div>
<%= f.submit %>
</div>
</div>
<% end %>
This lets you reuse the same form for updating the resource. Also when you use the input helpers rails will properly name the inputs so that you can whitelist them with:
params.require(:post).permit(:continent, :country, :title)
Can anyone see what's wrong with this form of expression?
<%= simple_fields_for :article do |f| %>
<%=f.input :q, :nil, placeholder: "Search" %>
<% end %>
Error message says:
wrong number of arguments (3 for 1..2)
So- my wider code is:
articles#index.html.erb:
<div class="row">
<div class="col-md-10 col-md-offset-1">
<%= render 'articles/searchform' %>
</div>
<div class="col-md-10 col-md-offset-1">
<% Article.all.sort_by(&:created_at).in_groups_of(3) do |group| %>
</div>
<div class="row">
<% group.compact.each do |article| %>
<div class="col-md-4">
<div class="indexdisplay">
<%= image_tag article.image_url, width: '100%', height:
'200px' if article.image.present? %>
<div class="indexheading"> <%= link_to article.title, article %> </div>
<div class="indexsubtext"> <%= truncate(article.body, :ommission =>
"...", :length => 250) %></div>
</div>
</div>
<% end %>
</div>
<div class="row">
<%= link_to 'New Article', new_article_path %>
</div>
In my views articles#form.html.erb
<div class="col-xs-10 col-xs-offset-1">
<%= simple_form_for(#article) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.input :title, autofocus: true %>
<%= f.input :body, :label => "Post", :input_html => {:rows => 10} %>
<%= f.input :image, :label => "Add an image" %>
</div>
<div class="form-actions">
<%= f.button :submit, "Review a draft", :class =>
'formsubmit' %>
</div>
<% end %>
In articles#searchform.html.erb
<% f.simple_fields_for :article do |a| %>
<%=a.input :q, :nil, placeholder: "Search" %>
<% end %>
I get this error:
undefined local variable or method `f' for #<#<Class:0x007f874133c410>:0x007f8740448058>
You are missing your form variable, e.g. f.
For instance if you have simple_form_for ... do |f| you should then write
= f.simple_fields_for :article do |article|
= article.input :q, :nil, placeholder: 'search'
[EDIT] You seem confused. The simple_fields_for is a special command to iterate over nested items, inside a form (e.g. comments for a post). So simple_fields_for would require a surrounding form (simple_form_for). For your search-form you should just be using simple_form_for.
I'm creating a simple form in rails and the submit button doesn't work. I think I'm missing something obvious here but the html seems to be fine (I'm far froma front end expert). Any advice or pointers?
<div class="container">
<div class="row">
<div class="col-lg-12 text-center">
<h2>Apply</h2>
<hr class="star-primary">
</div>
</div>
<div class="row">
<div class="col-lg-8 col-lg-offset-2">
<div class="row control-group">
<% if #user.errors.any? %>
<div id="error_explanation">
<div class="alert alert-error">
The form contains <%= pluralize(#user.errors.count, "error") %>.
</div>
<ul>
<% #user.errors.full_messages.each do |msg| %>
<li>* <%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="col-xs-12 floating-label-form-group controls">
<%= form_for #user, url: users_path(#user), :html => {:method => :post} do |f| %>
<%= f.label :name %>
<%= f.text_field :name, class: "form-control", placeholder: 'Name' %>
<%= f.label :email%>
<%= f.text_field :email, class: "form-control", placeholder: "Email" %>
<%= f.label :address%>
<%= f.text_field :address, class: "form-control", placeholder: "Address" %>
<%= f.label :phone %>
<%= f.text_field :phone, class: "form-control", placeholder: "Phone Number" %>
<%= f.submit "Apply"%>
<%end%>
</div>
</div>
</div>
</div>
</div>
Also, when the submit button fails, nothing happens. No error messages, no console errors. Nothing.
Take method out from the html hash?
form_for #user, url: users_path(#user), :method => :post do |f|
Try this:
<%= form_for #user, :url => {:controller => "your-controller-name", :action => "your-action-name"} do |f| %>
Can you try this one:
<%= form_for #user, url: {action: "create"} do |f| %>
...
...
<%= f.submit "Apply" %>
<% end %>
But I strongly suggest you to use simple_form gem.
I am adding partials to a show view, but I am getting errors of undefined methods that are inside the partials that are being called. I use the partials in other places and it works fine. I think I need to define a local variable, but I am not sure which one

</div>
</fieldset>
the errors I am getting in this partial specifically is :
undefined method `sku' for nil:NilClass
Like I said I think I need to define a local in my partial I just don't know the syntax
The locals syntax like this
<%= render :partial => "/ideas/copy_show", :locals => {:f => f} %>
now use f in your partial page
I have a view where I need to show a list of pages (I have a model called Page) and then i need the id of the selected page
I have this code in the view

<%= select_tag(:page, options_for_select(['a',1])) %>
<% end %>
#pageslist is a 2d array of the form [['pagename', 1], ..]
The question is how can i access the page_id of the selected page in the controller ?
I tried params[:p_id] but it is not working any help please?
This is what I have in the controller:
#task = Project.find(params[:project_id]).tasks.new(params[:task])
#task.update_attributes({:page_id => params[:p_id]})
Assuming that #pagelist is in a format as you described, then in your view:
<%= select_tag(:page, options_for_select( #pagelist )) %>
You had missed it in your example, and provided only 1d array for options_for_select.
With such prepared view your create action will receive page id in:
params[:page]
it's because you had passed :page as a first argument for select_tag.
