in_place_select with hash?

Hi Folks,

I have recently starting working with Flvorful's Super In Place Controls (http://os.flvorful.com/super_in_place_controls) and have a question with which I hope someone can help.

I would like to use either the in_place_select or in_place_radio and have it display one value, but record another. Without the in place editing, I might have have used a radio button to display "Active" while recording "1" in my database (using an integer to record the state instead of a string, obviously).

The rough code is this (this works correctly in that is displays and records the status integer correctly):

Status: </b><%= in_place_select :contestGroup, :status,   :choices => %w(0 1).map {|e| [e,e]} %>

I have been able to use the following some what successfully:

Status: </b><%= in_place_select :contestGroup, :status,   :choices => {"Disabled" => "0", "Active" => "1"}.each {|k,v| [k,v]} %>

This will correctly update the database with the new status, but the display in the select box is either "0" or "1". If I reverse the hash, naturally, I see "Disabled" or "Active" in the select box, but then the string -- not the number -- is passed back in the AJAX handler.

Finally, I only ever see a "0" or "1" before activating the in_place_select.

I would greatly appreciate if anyone with some experience with this plugin and has been able to control the display and update accurately could share some wisdom. :slight_smile:

I'm sure I have simply overlooked something.

Many thanks,

pdp

I found the solution (well, at least "a" solution). This post, Can't get select helper to populate dropdown w/default value - Rails - Ruby-Forum, identified that the "collect" method as the secret sauce.

Here's an example:

irb(main):037:0 testHash = {"public" => 0, "private" => 1} => {"public"=>0, "private"=>1} irb(main):038:0> eachResults = testHash.each { |k,v| [k,v] } => {"public"=>0, "private"=>1} irb(main):039:0> collectResults = testHash.collect { |k,v| [k,v] } => [["public", 0], ["private", 1]]

The nested array is what we need in the select helper. The each method returns the object instance while the collect method returns a new array.

I hope this helps someone in the future.

Yes, but not to the original question. I have the select box working correctly (displaying text and setting a number), but the display field (when the in_place_select is not active) is showing the value and not the display text.

Hi pdp,

did you manage to solve this? I have the same problem. Bugs the sh.. out of me too. Hope you or anyone else have a solution. Thanks

Hi Mike,

I picked up this code again after it sat unattended for a while.

I found that using the :display_text option solved the problem of showing an intelligent value in the selection list while retaining the ability to record the more efficient numerical representation to the database.

Here's how it looks now:

in_place_select :contestSeries, :status, :choices => {"Disabled" => "0", "Active => "1"}.collect {|k,v| [k,v]}, :display_text => convert_contest_series_status_codes(@contestSeries.status)

"convert_contest_series_status_codes" is a helper method used in a variety of locations to convert "0" to "Disabled" and "1" to "Active". Basically having something get the display string and pass it to :display_text shows the correct value in the selection list.

Unfortunately, the display_text does not update after the value is changed. One has to refresh the page after updating the value, so there is still some more work to do.
