select list

[marccantwell]

could you provide an example of how to hook up select list data? for example, I have:

<%= f.select :state, options_for_select( [[ "Select a State", "" ]] + State::NAMES )%>

in my form view for selecting states. How would I replicate this with the gem? The jeditable documentation shows how to load a url of that data, which I suppose I could do, but, I'm assuming it is possible to pull in something similar to what I have above.

Thanks in advance.

Yeah, so selects are a bit of a pain... the settings for the field are basically being passed directly to the jeditable plugin - check out the "How to use Selects?" section on its documentation page. jeditable expects a hash of keys and values, so currently an array needs to be converted. I have a helper in my application that creates this (see here) - this is what it would look like for your example:

def states_json_string
  # assuming State::NAMES => ['Alabama', 'Arkansas', ...]

  states_pairs = ["'': 'Select a state...'"]
  states_pairs.concat State::NAMES.collect{|s| "\"#{s}\": \"#{s}\""}
  "{#{states_pairs.join(', ')}}"
end

Then, the view code would look something like this (adapted from here):

editable_field @user, :state, :type => 'select', :data => states_json_string

This is something else that needs to handled by the gem. On the to-do list...

Are you still working on this gem?
We'd really benefit from the ability to edit selects as easy as text fields.
Also, I don't understand how State::NAMES would have to be set up :(

Sorry bout that - been meaning to come back and overhaul this gem for a while, but keeps getting pushed back on my to-do list. Will try to get to it soon - thanks for the patience.

No unnecessary hurry, we'll be developing that app for some more months ;)

If you could explain how you set up the State::Names thingie, that might already help to at least get the make shift running.

Hi! I have been using your gem (which is awesome by the way! thank you very much for making it), and encounter the same issue.
I want to share with you how I solved it in case you might find it useful.

• In your gem file include 'json' like the following:

  gem 'json' 

This is a gem that helps you convert any hash into a json string.

• Add a method in you controller similar to this one:

def json_hospitals(hospitals)
    hashHospitals = Hash.new
    hospitals.each do |hospital|
      hashHospitals[hospital.id] = hospital.name
    end
    return JSON.generate(hashHospitals)
end

This will grab all the hospitals that are in your database and put them in a hash. The hash is then converted and returned as a json string using: JSON.generate(nameOfYourHash)

• In your controller but in the method you want to use that json (in my case index) do the following:

 @hospitals = Hospital.all
 @stringHospitals = json_hospitals(@hospitals)

Here we can control what objects we are sending to the method json_hospitals. So if you only want to send the ones that are linked, let's say, to a particular location, you just have to change the query. Finally I store the returned json string into my varible @stringHospitals.

• Finally in the view you are using jeditable you just have to set the jeditable field as the following:

<%= editable_field hospitalname, :name, :type => 'select', :submit => 'OK', :data => @stringHospitals %>

Note that in the :data field I'm using the @stringHospitals I just created.

That's it!
I hope this helps!!!! :)

Again thank you so much for your gem it has helped a lot! :)

Big thanks, acemacu.

The select now works, only problem left is that i use the select to change an associated user (model) on the base model.
When i use it like this :

<%= editable_field @Property, :associate, :type => 'select', :submit => 'OK', :data => @json_users %>

...then it only displays a '#', even though you can click on it to get to the select. The controller complains about expecting a user and getting a string, so i change it to this:

<%= editable_field @Property, :associate_id, :type => 'select', :submit => 'OK', :data => @json_users %>

This actually works and changes the field in the database.
But then only the ID of the user is shown, not his name. Any idea how to get around this?

//edit

Also, how can I tell it to select a certain entry in the select? just adding ' :select => @property.associate.id ' doesnt work :/
