Rails 4 - best_in_place: Unprocessable Entity

Question

I'm using best_in_place to edit a field in a profile database managed with 'devise'. Everything updates fine in the edit view, but shortly after editing a single field with best_in_place the field returns to its original value, and the database has not been updated.

NOTE: Running bundle install, restarting the server, and refreshing the page have not worked.

users_controller.rb:

class UsersController < ApplicationController    
respond_to :html, :json

...

    def update
    @user = User.find_by_id(params[:id])

        respond_to do |format|
        if @user.update_attributes(user_params)
            format.html { redirect_to(@user, :notice => 'Profiiile was successfully updated.') }
            format.json { head :ok }
        else
            format.html { render :action => "show" }
            format.json { render :json => @user.errors.full_messages, :status => :unprocessable_entity }
            end
        end
    end

...

private
    def user_params
        params.require(:user).permit(
            :id,
            :first,
            :last,
            :email,
            :password,
            :password_confirmation,
            :remember_me,
            :user_phone,
            :user_birthday,
            :user_gender,
            :user_street_address,
            :user_city,
            :user_state,
        )
    end
end

users.js.coffee:

jQuery ->
    $('.best_in_place').best_in_place()

users/show.html.erb

<section id="header">
    <div class="row title">
        <div class="large-12 column">
            <h1><%= best_in_place @user, :first %> <%= best_in_place @user, :last %></h1>
        </div>
    </div>
</section>

Javascript error console shows:

Thank you in advance for any help.

Try replacing:

    format.json { head :ok }

with:

    format.json { respond_with_bip(@user) }

in your respond_to block in your controller.

respond_with_bip is a "utility method you should use in your controller in order to provide the response that is expected by the javascript side, using the :json format" https://github.com/bernat/best_in_place

EDIT:

Hmm, it might be that devise is expecting a password to update the user, and this is causing the rollback, since it can't find one. You can do one of two things: remove :validatable from devise in your User model, or add these two validation overrides to your User model, validates :password, presence: true, length: {minimum: 5, maximum: 120}, on: :create validates :password, length: {minimum: 5, maximum: 120}, on: :update, allow_blank: true
