I have a rails app where user can assign task to another user by creating task action. At the moment I have the f.collection_select, but as the number of users grows it won't be a good solution. I would like to change it into kinda search form. My problem is that I don't see how I can do this. I have other search forms, but those are for show/index action. How can I do this for the create action?
here is my current code:
<%= form_for ([#user, #task]) do |f| %>
<%= render 'layouts/error_messages', object: f.object %>
<div class="field form-group">
<%= f.label :executor_id %>
<%= f.collection_select(:executor_id, User.all, :id, :email, class: "form-control") %>
</div>
<div class="field form-group">
<%= f.label :content %>
<%= f.text_area :content, class: "form-control" %>
</div>
<div class="field form-group">
<%= f.label :deadline %>
<%= f.date_select :deadline, class: "form-control" %>
</div>
<div class="actions">
<%= f.submit "Create Task", class: 'btn btn-primary', "data-sid" => current_user.id, "data-rip" => :executor_id %>
</div>
<% end %>

<%= form_for #poll do |f| %>
<%= render 'shared/errors', object: #poll %>
<div class="form-group">
<%= f.label :topic %>
<%= f.text_area :topic, rows: 3, required: true, class: 'form-control' %>
</div>
<div class="panel panel-default">
<div class="panel-heading">Options</div>
<div class="panel-body">
<%= f.fields_for :vote_options do |options_form| %>
<%= render 'vote_option_fields', f: options_form %>
<% end %>
<div class="links">
<%= link_to_add_association 'add option', f, :vote_options%>
</div>
</div>
</div>
<%= f.submit 'Create', class: 'btn btn-primary btn-lg' %>
<% end %>
link_to_add_association doesn't work. It shows that the template is missing when the template is actually present.
Here is my _vote_option_field.html.erb
<div class="nested-fields">
<div class="form-group">
<%= f.label :title %>
<%= f.text_field :title, class: 'form-control', required: true %>
</div>
<%= link_to_remove_association "remove option", f %>
</div>
Maybe you can add the partial path as html_options. Something like this:
<div class="links">
<%= link_to_add_association 'add option', f, :vote_options, partial: 'your/partial/path'%>
</div>`

I am trying to figure out how to access a virtual attribute from params.
In my books_controller.rb, I have:
wrap_parameters :books_list
def product_params
params.require(:product).permit(:author_name, :book_name, :books_list)
end
Obviously, the books_list is the virtual attribute. I will be saving it to the books_list table
In my new.html.erb,I have:
<% #title = "Books" %>
<div class="container">
<div class="row">
<div class="col-xs-12 col-sm-12 col-md-12 col-lg-12">
<%= form_for(#books, html: { class: 'form-horizontal' }) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.form_group :author_name do |f| %>
<%= f.label :author_name, class: 'control-label col-md-2' %>
<div class='col-md-8'>
<%= f.text_field :author_name, class: 'form-control' %>
<%= f.error_messages %>
</div>
<% end %>
<div class="form-inputs">
<%= f.form_group :book_name do |f| %>
<%= f.label :book_name, class: 'control-label col-md-2' %>
<div class='col-md-8'>
<%= f.text_field :book_name, class: 'form-control' %>
<%= f.error_messages %>
</div>
<% end %>
<%= f.form_group :books_list do |f| %>
<%= f.label :books_list, class: 'control-label col-md-2' %>
<div class='col-md-8'>
<%= f.text_area :books_list, class: 'form-control' %>
<%= f.error_messages %>
</div>
<% end %>
</div>
<div class="form-actions col-md-offset-2 col-md-10">
<%= f.submit class: 'btn btn-primary' %>
<%= link_to "Cancel", test_sets_path, class: 'btn' %>
</div>
<% end %>
</div>
</div>
</div>
When I submit the form, here's what I get for params:
Parameters: {
"utf8"=>"✓",
"authenticity_token"=>"5mxkibQHkwRnzVU31A6pe9uezsmaWeYbCUgU+gUZPLmiAZPnN6si+smdEePU0lfGITh7gmmyChf/bOY+YQQcQg==",
"books"=>{"author_name"=>"Some Author", "book_name"=>"Dwan Of The Dead"},
"books_list"=>{"{:class=>\"form-control\"}"=>"book1\r\nbook2"},
"commit"=>"Create Book List"
}
I am having trouble accessing the books_list in params. Any ideas?
If books_list column is not exist in #book, it raises error.
There is no method f.form_group in rails, I think you use gem that defines form_group method.
Maybe "books_list"=>{"{:class=>\"form-control\"}"=>"book1\r\nbook2"} parameter is made by some bootstrap gem. you check check name attribute in html source.
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 have to pass a value in a form where the user cannot to choose. I have a Register model with some fields. One of them is a value from another Model called Car. I show in the _form view the car plate value but I want to link this value in the form This is the code in _form :
<%= form_for(#reg) do |f| %>
<div class="field">
<p><%= f.label :date %></p><br>
<%= f.date_field :date_reg %>
</div>
<div class="field">
<p><%= f.label :car_id %></p><br>
<% Car.all.each do |car| %>
<%= car.plate %>
<%= f.select(:driver_id,
options_from_collection_for_select(Driver.all, :id,
:name), {:prompt => 'Please Choose'}, :class => "form-
control") %><br>
<% end %>
</div>
<div class="field">
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Thanks all
my view is
<h3> Register New Items </h3>
<div class="row">
<div class="span2 offset4">
<%= nested_form_for #item_category, :url => items_path, :method => :post, :html => { :class => "item_category"} do |f| %>
<div><%= f.label :item_name %>
<%= f.text_field :item_name %></div>
</br>
<div>
<%= f.fields_for :item_companies do |f| %>
<%= f.label :company_name %>
<%= f.text_field :company_name %>
</div>
</br>
<%= f.fields_for :item_weights do |f| %>
<div>
<%= f.label :weight %>
<%= f.text_field :weight %>
</div>
</br>
<div>
<%= f.label :price %>
<%= f.text_field :price %>
</div>
<%end%>
<%end%>
<div><%= f.submit "Submit" %></div>
<% end %>
</div>
and controller
def new
#item_category = ItemCategory.new
item_company = #item_category.item_companies.build
item_company.item_weights.build
end
and when I have applied debugger in create action and I saw value of params[:item_category] and this is generated {"item_name"=>"iname", "item_companies_attributes"=>{"0"=>{"company_name"=>"cname", "item_weights_attributes"=>{"0"=>{"weight"=>"20kg", "price"=>"100"}}}}}
ItemCategory.new(params[:item_category])
generated error
ActiveModel::MassAssignmentSecurity::Error Exception: Can't mass-assign protected attributes: item_companies_attributes.
Where i am wrong and how to save value in three tables using this.
It seems that you forgot to add this piece of code in your ItemCategory model:
attr_accessible :item_companies_attributes
which will allow you to set these attributes.
