Dynamic saving settings

[NicoBijl]

i am building an app and want to give the users the possibility to change there settings, so i want to save from a form with this code:

params[:settings].each do |key, value|
Settings.instance_variable_set("@#{key}", value)
end

do i need to call a save method?? Settings.save?

Because it wont work like this...

I just did this like this:

params[:settings].each do |key, value|
    Settings[key] = value
end

Works wonderfully!

I am struggling with making this work in my app. I would like to have a "system-wide" settings page, where administrators could change system settings (not related to users) via some kind of form.

I have created controller with index an update actions, but i can't manage to process what form send in the update action. Currently, i have a problem with UTF-8 and a check mark thing.

would anyone be so kind a help me make this work.

OMG, this was fast. I am looking forward to see how it is done. Thanks a million!

i was driving...

here the code:

view: <%= form_tag(update_settings_path) do %> <% @settings.each do |key, value| %>

<%= label_tag key %>
<%= text_area_tag key, value %>

<% end %>

<%= submit_tag("Save Changes") %>

<% end %>

controller: class SettingsController < ApplicationController def index @settings = Setting.all end def update Setting.all.each do |key, value| eval("Setting.#{key} = params[key]") end redirect_to settings_path, :notice => 'Settings updated' # Redirect to the settings index end end

Hey, tnaks for this. Looks very similar to what i was trying. One more question though - how do i have to set my routes? Do I just add resources :settings, or do i have to make a custom route? Maybe a collection? This is a part i just don't get how to do properly.

Thanks!

I can get update_settings_path to work. Am getting undefined local variable or method `update_setting_path' for #<#Class:0x5386128:0x3abf7c8>

[Svashta]

Ok, now i am having some progress. I have made routes like this:

resources :settings do collection do put :update_all end end

An in form i now have - form_tag(update_all_settings_path, :method => :put)

Form does work now, and something is being processed, but the value is now null. I'll look further into it in the controller.

Send me your view and controller

I had an impression i don't need it as it is somehow handled by the gem. Seemed weird, but yeah ... don't have it actually.

[Svashta]

Hey,

i have now reverted back to your code completely and added Setting model (class Setting < ActiveRecord::Base). I am now again having update_settings_path undefined local variable or method error.

What's with that. I don't get it anymore.

[Svashta]

Yay. Got it. Finally. Your code + collection in resource for setting with defined put action = win. Thanks!

[sasharevzin]

Cool

Ps. Sorry, I wasn't able to answer u before cuz had a training ;)

Please try release 2.0.0, which is a complete rewrite. Editing settings via forms is much simpler now, because settings are ActiveRecord instances, too.
