I have a Rails 3 application with a view that is irritating me. The view is essentially four tabs. Each tab shows a filtered list of records like this:
Tab One
<% #faults.each do |fault| %>
<%= fault.name %>
<% end %>
Tab Two
<% #faults_pending.each do |fault| %>
<%= fault.name %>
<% end %>
Tab Three
<% #faults_closed.each do |fault| %>
<%= fault.name %>
<% end %>
Obviously there is a lot more code that I have missed out. To tidy the view up significantly I considered making a partial for each tab, however, each of those partials would be identical except for the <% #faults.each do |fault| %> line.
Is there a way of having one partial and somehow when rendering the partial set the scope (or method, I can never remember what it's called).
I think you're looking for render's :locals option.
Tab one
<%= render :partial => "faults", :locals => { :faults => #faults } %>
Tab two
<%= render :partial => "faults", :locals => { :faults => #faults_pending } %>
Tab three
<%= render :partial => "faults", :locals => { :faults => #faults_closed } %>
Partial
<% faults.each do |fault| %>
<%= fault.name %>
<% end %>

I am using a single form for new and edit actions in my controller.
edit.html.erb
<%= form_for #user, :url => edit_users_path(#user) do |f| %>
<%= render :partial => 'form', :object => f %>
<%= f.submit "Update" %>
<% end %>
new.html.erb
<%= form_for #user, :url => users_path do |f| %>
<%= render :partial => 'form', :object => f %>
<%= f.submit "Submit" %>
<% end %>
_form.html.erb
<%= form.text_field :firstname %>
<%= form.text_field :lastname %>
<%= form.email_field :email %>
For boths the actions, submit doesn't work. The form is rendered fine. I added data from rails console to check for edit. It doesn't work either.
If I create 2 separate form for each, new & edit, it works fine. So i assume my controller code is fine.
Thanks
Render the partial with:
<%= render :partial => 'form', :form => f %>
instead. If it doesn't work, check the input names in the generated HTML.
I see in your edit and new files are using an |f| variable for the form builder but in the form partial you're using form as the variable. Try changing the fields in your partial to "f.text_field"
I am running into issues trying to separate a form from a view into a partial. I want to use the same form for the new and edit views. These are both on the same page. The new model form is at the top of the page and uses a variable that I set in the controller.
<%= form_for #new_hire do |f| %>
<%= render :partial => 'new_hire_requests/form', :locals => {:f => f} %>
<% end %>
I then have a partial for the pending approvals that gets rendered by another partial
<%= render :partial => 'pending_approval', :collection => #pending_approval %>
And inside the pending approval partial I have this
<%= form_for pending_approval do |f| %>
<%= render :partial => 'new_hire_requests/form', :locals => {:f => f} %>
<% end %>
This is throwing an error
undefined method `new_hire_request_path' for #<#<Class:0x0000010488ac98>:0x0000010223ffc0>
Is there a way to re use the form code for both a new and edit form on the same page?
Controller Logic
#new_hire = NewHireRequest.new
#new_hire_requests = current_user.new_hire_requests
#pending_approval = #new_hire_requests.select{|p| p.status == 'pending_hr_approval' || p.status == 'pending_exec_approval'}
Partial code
<%= render 'shared/error_messages', object: f.object %>
<fieldset class="first">
<%= f.label :first_name, "First Name" %>
<%= f.text_field :first_name %>
</fieldset>
<fieldset>
<%= f.label :last_name, "Last Name" %>
<%= f.text_field :last_name %>
</fieldset>
<%= f.submit "Submit for Approval <i class='icon-share-alt icon-white'></i>",
class: "button_green" %>
add resources new_hire_requests in the routes and get done with it .
I have a Post which can have multiple Tags, each of which relates to a User (think Facebook tagging).
In my Post form I have this Formtastic code:
<%= f.inputs :class => 'tags' do %>
<ul>
<%= f.semantic_fields_for :tags do |t| %>
<% if t.object.new_record? %>
<%= t.input :user_id, :label => " ", :input_html => { :class => 'chosen', :'data-placeholder' => 'Select connection' }, :as => :select, :collection => current_user.connections %>
<% end %>
<% end %>
</ul>
<% if #post.tags.present? && !#post.new_record? %>
<ul class="existing-tags">
<%= f.fields_for :tags do |t| %>
<% unless t.object.new_record? %>
<li>
<%= link_to avatar(t.object.user), user_path(t.object.user) %>
<%= t.check_box :_destroy %>
<%= t.label :_destroy, 'Remove' %>
</li>
<% end %>
<% end %>
</ul>
<% end %>
<% end %>
As you can see this can allow a tag to be added one at a time. However I'd like to allow multiple selections in the dropdown menu, to create multiple tags in one go. Adding "multiple" doesn't work, however: it simply results in creating a tag for the current user, posting the Post.
Can anyone suggest a way I can use a single select field to create multiple tags?
A bit late to the party, but I solved this problem using the awesome jQuery Chosen plugin which makes multiple selects look really good.
I have a partial that I use to show errors from an object onto a form.
<% if object.errors.any? %>
<div id="error_explanation">
<h2>Oops, looks like <%= pluralize(object.errors.count, "error") %>
occured:</h2>
<br />
<ul>
<% object.errors.each do |key, msg| %>
<li><%=key%><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
It works great for 1 model.
However I can't figure out how to make it work for a form that has two models.
Any ideas? I don't want to use the plugin I would like to have more control.
Just output the partial for each model in the form view with 2 models and pass actual model instances into this partial as local variable:
<%= render :partial => 'name_of_partial_to_show_model_errors', :locals => {:object => #model1} %>
<%= render :partial => 'name_of_partial_to_show_model_errors', :locals => {:object => #model2} %>
Trying to make a nested form, which is working fine so far, except i need to put some dropdowns for the user to choose, as well as maybe make a couple of validations, however it seems nothing gets out of the form properly and keep getting errors no matter what I try.
three models.
--configuration
has_many :configoptions
accepts_nested_attributes_for :configoptions
--configoption
belongs_to :configuration
has_many :items
and item
belongs_to :configoption
scope :sorted, order('items.position ASC')
Now, so far I'm creating a nested form, looping through the configoptions, but for each option is possible there's more than one item. So I want to make a drop-down for those options where this is the case.
In my view i have:
<p>
<th>Elements</th>
<th>Quantity</th>
</p>
<%= form_for #config, :url => {:action => 'show', :id => #config.id} do |f| %>
<%= f.fields_for :configoptions do |fp| %>
<p>
<% if :items.count > 1 %>
<%= fp.text_field :name %>
<% else %>
<% fp.select(:items, :name)%>
<% end %>
<%= fp.text_field :quantity %>
</p>
<% end %>
<%= f.submit %>
<% end %>
I get an error obviously telling me that it can't count the :items.
How do you think I can make this work?
Thanks!
<%= form_for #config, :url => {:action => 'show', :id => #config.id} do |f| %>
<%= f.fields_for :configoptions do |fp| %>
<%= fp.text_field :id %>
<%= fp.text_field :name %>
<%= fp.text_field :quantity %>
<% end %>
<%= f.submit %>
<% end %>
OK, I think I figured it out, at least it seems to be doing what I want now.
I modified the view to pass the instance of the configoption into the nested form itself to be able to create the drop downs.
<% for configoption in #config.configoptions %>
<%= f.fields_for :configoptions, configoption do |fp| %>
<p>
<% if configoption.items.count > 1 %>
<%= fp.select (:name, options_from_collection_for_select(configoption.items.sorted, 'name', 'name'))%>
<% else %>
