Listing Model - belongs_to :area
Area Model - has_many :listings
I'm trying to implement a search using Ransack with check boxes; where user checks selected areas, search returns all the listings of the areas selected.
<%= search_form_for #search do |f| %>
<% areas = Area.all %>
<% areas.each do |area| %>
<%= check_box_tag('q[area_id_eq][]', area.id) %>
<%= area.location%>
<% end%>
<%= f.submit "SEARCH" %>
<% end %>
Console output:
Parameters: {"utf8"=>"✓", "q"=>{"area_id_eq"=>["1", "2"]}, "commit"=>"SEARCH"}
Completed 500 Internal Server Error in 4ms
NoMethodError - undefined method `to_i' for ["1", "2"]:Array:
Just not sure how to implement it to accept multiple check box values.
Instead of using "area_id_eq", use "area_id_any". You'll also want to check to make sure that your parameters are selected:
<%= search_form_for #search do |f| %>
<% areas = Area.all %>
<% areas.each do |area| %>
<%= check_box_tag('q[area_id_eq_any][]', area.id, (params[:q][area_id_eq_any].include? area.id.to_s) ? true : false ) %>
<%= area.location%>
<% end%>
<%= f.submit "SEARCH" %>
<% end %>

I have a rails app where I can create and edit records. I've created a form to enter data which works fine when I use the new/create actions. It will create a record no problem. But when I hit the edit action it gives me an undefined method 'model_name' for NilClass:Class.
I'm not sure what this means. Can someone give me a hand?
Form:
<%= form_for(#patient) do |f| %>
<%= f.label :Patient_Last_Name %>
<%= f.text_field :patient_last %>
<%= f.label :Patient_First_Name %>
<%= f.text_field :patient_first %>
<%= f.label :Patient_DOB %>
<%= f.date_select :patient_dob %>
<%= f.label :Primary_Diagnosis %>
<%= f.collection_select(:diagnosis_id, Diagnosis.all, :id, :diagnosis_name)%></br>
<%= f.label :Primary_Physician %>
<%= f.collection_select(:physician_id, Physician.all, :id, :physician_name)%></br>
<%= f.button :submit %>
<% end %>
View Code:
<td><%= link_to 'Edit', edit_patient_path(patient), :class => 'btn btn-close btn-mini'%></td>
Controller Code:
def edit
#patient = Patient.find(params[:id])
end
Edit view:
<%= render 'form' %>
When I remove the partial render from the form, the URL will go to the correct route/url. But I keep getting that error when the form partial is rendered.
There was an extra end statement in my controller which was cutting off half of the class which included the edit action. This was not allowing me to use the edit action. Once this typo was fixed things started working normally.
Sorry for the confusion.
I am building an application in which when the user log in as an admin it will have the list of registered users and have four links show,edit destroy and settings.What i want is when the admin click on the settings link it will have the view of check boxes in which admin decides the permission of users to read,edit,create and destroy of the model available in an application.
Thanks in advance.
If I understand you correctly you are looking for a view that sets the settings for one user.
Since you didn't give any details on your model I'll assume the Model is called User and the permissions are just boolean fields on that model.
Similar to this:
User
- can_read
- can_create
- can_destroy
- can_edit
I would then implement the view like this:
<%= form_for #user do |f| %>
<%= flabel :can_read %>
<%= f.check_box :can_read %>
<%= flabel :can_create %>
<%= f.check_box :can_create %>
....
<%= f.submit %>
<% end %>
Or shorter:
<%= form_for #user do |f| %>
<% [:can_read, :can_create, :can_edit, :can_delete].each do |permission| %>
<%= flabel permission %>
<%= f.check_box permission %>
<% end %>
<%= f.submit %>
<% end %>
The controller code would obviously look like this:
def edit
#user = User.find(params[:id]
end
def update
#user = User.find(params[:id]
#user.update_attributes(params[:user])
end
I'm pulling a list of categories from a model.
In the admin section I want to use it to assign categories to products.
It's working fine but the list shows in the order the categories have been added.
I'd like to sort them alphabetically but I can't suss it out.
I'm sure it's pretty simple (hopefully)
here's my code:
<%= simple_form_for(#game) do |f| %>
<%= f.input :name %>
<%= f.input :description %>
<%= f.input :copy %>
<%= f.input :image %>
<%= f.input :thumbnail %>
<%= f.input :heroimage %>
<%= f.association :category, collection: #categories %>
<%= f.button :submit %>
<% end %>
I tried to add a .sort_by(desc) or just .sort on the collection method but it doesn't change the list.
Cheers
Here is how you should update your code:
<%= f.association :category, collection: Category.order('name ASC') %>
This assumes you want to sort by the category name, in ascending order.
I imagine #categories is assigned as an arel in your controller, can you add an .order("description") to that; e.g.
#categories = Category.order('description')
Guys my check_box_tag looks like as follows
<%= form_tag({:action => 'update_survey_list_status',:projectid=>params[:id], :status=>4}, :id => 'to_be_approved_frm') do %>
<% #publishedlist.each do |b| %>
<%= fields_for "beneficiaryloan[#{b.id}]" do |bloan| %>
<%= bloan.text_field :amount, :class=>'forms_txtbx'%>
<%= bloan.text_field :rate, :class=>'forms_txtbx'%>
<%= bloan.text_field :period, :class=>'forms_txtbx'%>
<% end %>
<%= check_box_tag "benificiary_id[#{b.id}]",b.id,:name => "benificiary_id[]"%>
<% end %>
<%= submit_tag "Approve", :class=>'form_buttons' %>
<% end %>
And in controller, I'm reading all the beneficiary ids like this
params[:beneficiaryloan].each do |key, value|
beneficiary = Beneficiary.find(key) rescue nil
#benefciary_loan=beneficiary.beneficiaryloans.build(value)
#benefciary_loan.beneficiary_id=beneficiary.id
#benefciary_loan.hfi_id=session[:id].to_s
#benefciary_loan.status_id=params[:status]
#benefciary_loan.save if beneficiary
end
What I need is, Inserting all the beneficiary ids to [beneficiaryloans] table which are checked, but in my case it inserting all records even some of them are unchecked.
How to do I select only checked ids?
Try changing your check_box_tag to
<%= check_box_tag "beneficiaryloan[#{b.id}][enabled]", 1, true %>
Then in your controller do the following:
params[:beneficiaryloan].select{|k,v| v.delete(:enabled).to_i > 0 }.each do |k,v|
..
end
Since the enabled attribute has no influence in the model you can just delete it out of the resulting beneficiary_load hashes.
form with the single submit. How to store that values in the data base
<%= form_for (#movie) do |f| %>
//Movie
<%= f.label :moviename,"Movie Name:"%>
<%= f.text_field :moviename%>
//Releases
<%= f.fields_for :release do |release_fields| %>
<%= release_fields.label :theatre,"Theatre :"%>
<%= release_fields.text_field:theatre%>
<%= release_fields.label :city,"City :"%>
<%= release_fields.text_field:city%>
<%= release_fields.label :releasedate,"Release Date :"%>
<%= release_fields.text_field:releasedate%>
//Submit:
<%= f.submit "Save The Movie"%>
<% end %>
<% end %>
