similar to: Having a problem adding a foreign key

There''s a number of calls in the Rails source to convert_to_model, which takes an activerecord object instance: convert_to_model(object) Here''s the thing. All convert_to_model does is calls to_model, which returns self (the ActiveModel instance). Am I missing something here? Why call a method that returns the same thing? @user => #<User id: 3, name:

I have installed active admin and also add my model -controller rate_professor there.......I can add/delete/edit data using active admin ...but if I click on submit button of my form in rate_professor controller ... I can see whatever I added in the index page ........but I don''t want to see that one.....I want to find the information(whatever I added by clicking submit button) on

Hi, While I was hacking ovirt-server, I have found that it's currently restricted to Postgres DB. Even if I like postgres for serious work on a server, I really prefer to hack/dev locally on a Sqlite or MySQL DB. I have googled on rails in order to find a good answer for the "foreign key problem" which forces OVirt to stay on pg. I have found a plugin on this particular

Hi! I''m using Migration to define my database schema and these "ALTER TABLE t ADD FOREIGN KEY..." look really ugly - that''s why I wanted to ask it would be possible to simply add add_foreign_key method to ActiveRecord? Are there any reasons this isn''t yet implemented? Greetings, Esad -- Posted via http://www.ruby-forum.com/.

Hello! I''m working on my first Rails app and I have a question regarding authentication. I already have authentication for signing up, logging in, logging out, etc. What I need is an account email activation function and a reset password (forgot password) function. I have read a little bit about Devise and watched the Railscast episodes on it, it seems nice, but is it possible to add

I need to select 1 record from each client. This record has the charge with the most severe charge type (lowest charge_type_id). How do I go about this? I have been using a find_by_sql query out of the client.rb that looks like: SELECT c.f_name AS f_name, c.l_name AS l_name, c.gender AS gender, c.race AS race, c.dob AS dob, c.address AS address, c.city AS city, c.state AS

Hi Guys, In my devise applications in Rails 3, I created a separate form under my SettingsController class of which it handles the ''Change Password'' of the User Model, so i can manipulate the current_user in the SettingsController. Now, I followed the set-up in the Devise/Views on how to update the form using ''Change password'' and either way update User for

Hi for my app, I have several tables for users (franceusers, belgiumusers, ...) and I would like to use one or another depending on domain I tried with table_name_prefix and table_name but it seems to not work class User < ActiveRecord::Base rolify # Include default devise modules. Others available are: # :token_authenticatable, :confirmable, # :lockable, :timeoutable and

I use Oracle and i really want to use migrations, but there seems to be no way to setup foreign key constraints. Is this true? If it is then doesn''t that make migrations useles with Oracle? Thanks Chris -- Posted via http://www.ruby-forum.com/.

Hello (I''m new to this group so please pardon any inappropriateness), I''m a primary maintainer of the schema_plus gem<https://github.com/lomba/schema_plus/>, which adds some capabilities to rails'' schema definitions. The gem has been around for several years and is pretty reliable. I''ve been wondering whether there''d be interest in folding

Is there any work being done to add support for defining foreign keys in ActiveRecord Migrations? If not is it something that people would find useful or do most people here believe in the "Application Database" style over the "Integration Database" style [1] as defined by Fowler? I''d love to see support for foreign keys in Migrations. For selfish reasons

Is there any reason why AR has never supported foreign-key constraints? I can understand the lack of support for triggers and stored procedures since they are highly dependent on the database to create a wrap API around them. But this is not the case for foreign keys. This is specially important for open-source projects like Redmine/Chiliproject and Gitorious where you shouldn''t be

I am regularly running into a problem where I can't seem to figure out how maintain correct data order when selecting data out of a dataframe. The below code shows an example of trying to pull data from a dataframe using ordered zip codes. My problem is returning the pulled data in the correct order. This is a very simple example, but it illustrates a regular problem that I am running into.

Quick question. Say I have a geographical database with counties and zip codes where counties have and belong to many zip codes. zip_codes (id, zip_code) counties (id, name) When I create the association table, the Rails way says to do the following: counties_zip_codes (county_id, zip_code_id). However, given that zip_codes.zip_code is itself a candidate key, I would much prefer to do the

i've search the email archives, searched the documention of various map packages and done an R-site search, but have been unable to find direct resources for creating maps of the US that are colored or annotated or ... by zipcode data. For example, create a map of the US and color each zipcode region by its population using two vectors z,p containing the zipcode and population,

on previous apps i hadn''t really worried much about adding foreign key indexes on my tables just because they''ve been fairly small and i didn''t really think i needed them. well, i''m working on something now that has the potential to have a lot more data, and a lot more foreign keys. so i have 3 tables... users, projects, and tasks.. should i be using add_index

Is there any package that I could use for zipcode search. I want to display schools that near a particular zipcode. I have no idea how to do this. It will be great if anyone can point me where I could find info -- Rgds, --Siva Jagadeesan http://www.varcasa.com/ Education Through Collabration -------------- next part -------------- An HTML attachment was scrubbed...

I am interested in locating a script to implement a sampling scheme that would basically make it more likely that a particular observation is chosen based on a weight associated with the observation. I am trying to select a sample of ~30 census blocks from each ZIP code area based on the proportion of women in a ZCTA living in a particular block. I want to make it more likely that a block will

This is a stupid question I know, but it is driving me crazy - I am missing something simple and basic here. I am trying to update missing zip codes on a data table. I am doing something incorrectly as the data in the Source table is not being updated, only the value in the array is changed. How do I get this to update the actual DB record instead? def add_missing_zips #find all records in

Hi everyone, For one of our projects we have a need to deploy and maintain a demo. As a result I''ve attempted to setup a set of rake tasks for the job. My goal is have one rake task called "deploy_demo" which purges the database, migrates to the current schema, and loads the db from a set of fixture files in a specified location. I''ve written two new tasks the perform
