ruby-on-rails – strong_parameters in Rails using datetime

Question:

I'm using strong_parameters to create a nested shape object in a form . All my attributes work correctly except those defined in datetime .

Is there anything special about receiving nested datetime ?

Looking at the console, the attribute is being nested correctly, but it comes with the Ni specification, with N from 1 to 6 depending on which parameter it refers to (year, month, day…), but when creating the object ( INSERT INTO ), the attribute specified in datetime does not appear:

Processing by ReleasesController#create as HTML
Parameters: {"utf8"=>"✓", ... "release"=>{ ... "qm_attributes"=>{"user_id"=>"1", "start_at(1i)"=>"2014", "start_at(2i)"=>"3", "start_at(3i)"=>"31", "start_at(4i)"=>"14", "start_at(5i)"=>"57", "end_at(1i)"=>"2014", "end_at(2i)"=>"3", "end_at(3i)"=>"31", "end_at(4i)"=>"14", "end_at(5i)"=>"57", ... }}, "commit"=>"Create Release"}

SQL (0.3ms)  INSERT INTO "qms" ("created_at", "release_id", "tipo_qm_release", "updated_at", "user_id") VALUES (?, ?, ?, ?, ?)

Answer:

I found that the html datetime_selector doesn't work for objects nested in the form. When I passed the date by text everything worked fine, parsing the datetime correctly. If anyone has questions about the whole process of using strong_parameters , I can be more specific.
