similar to: "validates_presence_of" not working

Hi everybody, I just started thinking about a project and am seeking some help regarding its design. The idea would be to create labels (i.e. address labels).I could let users type the text manually, but I dont think they would appreciate that when they''ll want to print 5000 addresses. I can also probably let them import csv files, that should not be a problem, but playing with those

I have been trying to model a labeled graph using ActiveRecord (trunk version). Basically, I have a ''Node'' model which represents a node linking to other nodes. Links (aka edges) are labeled (i.e., have a ''label'' attribute and other behavior). Thus I decided to model edges as an ''Edge'' model and use a ''has_many :trough''

I have a model that contains a :boolean field. In my view, I have a simple select of Yes or No, which equates to true or false, respectively. If I choose yes and save, everything works great. If I choose no, my model fails validation as I have this set as a required field using validates_presence_of. I have checked the log and it''s definitely set to false, why would this fail validation?

Is there an expert validater that can point me in the right direction? I''ve looked for extended documentation on ''validates_presence_of'' but i can''t seem to find any. I''m trying to make sure that i don''t enter a nil object in my database, so i''ve added validate_presence_of to my Record Model. i.e. --> class Record <

I have this in a model validates_uniqueness_of :aspect, :scope => :user_id In an instance method of the same model I have "save!" but I don''t touch the :aspect attribute in that instance method at all. Whenever that save! command is run however I get this error: ActiveRecord::RecordInvalid: Validation failed: Aspect has already been taken I don''t

Hi all, I just begun with RoR and going through the Agile development w Rails depot example ATM. I did everything according to the book (i believe), and after 3 hours of googling, reading docs, making sure i did everything correctly i can not make the validate_presence_of() to work - at least not as it looks in the book. My Product model looks like: class Product < ActiveRecord::Base

After creating a table in a create table migration, I''m then attempting to populate a couple of rows of data in the table using the create method. The first row gets inserted into the database, but any further calls generate a select against the database, but no insert. Am I doing something wrong, or is it inappropriate to create more than a single row of data in a table using

Is it possible to change error messages for Validation helpers? I am writing an app against a existing database (so no control over column names), but when there is validation error (e.g. with validate_presence_of) I would like to customize the field name. For example for telephone whose field name is PhoneNumber I would like to chnage it to "Telephone Number cannot be empty" rather

Last night a friend of mine started ranting about validates_presence_of :boolean_field returning not valid when the boolean field is false. I checked the rails issues and this seems to be a pretty common concern about the naming of ''presence'' . Instead of changing the behaviour of the presence validator, I was wondering if maybe the answer to avoid such misconceptions could be

I want to create a migration file that creates multiple tables, so i''m guessing the correct format would be: Can anyone confirm ? I''m guessing that each new create script requires a seperate class so formatted this way. Perhaps I''m wrong. TIA Stuart class CreateTable1 < ActiveRecord::Migration def self.up create_table :table1s do |t| t.column :length,

How would I go about adding validation, so if no tags are specified it will fail. I know I have to use validates_presence_of :tags - but not in the controller.. so I tried to generate a model called

I have a form with 3 fields: user_id, email and password. All 3 fields are required, so I have a "validates_presence_of :user_id, :email, :password" in my model. Works, but the validation errors show up in a different order than I specificed in the validates_presence_of statement. Is there a way to specify the order in which the validations (and corresponding error messages) should
