similar to: form with saved and new model instances

Howdy Folks, I want to use form_for to allow a user to submit a form that contains two instances of the same model. They are entering calendar dates and I want them to be able to submit 2 from the same form. Ok, so, using form_for, what is the best way to do this? form_for seems to be setup to handle a single instance in that it wants a name for the variable, etc... Has someone else done this?

I''m having trouble with a validation that depends on an attribute of a belongs_to parent. If the child is added to an unsaved parent (parent.children << new child), the has_many collection parent.children includes the unsaved child. However the belongs_to attribute child.parent appears to be nil until the parent has been saved. Without access to the parent attributes, the validation

In a belongs_to association, is there a way to tell if the associated object was newly created? Hopefully this will explain my question: A Firm class declares has_many<http://api.rubyonrails.com/classes/ActiveRecord/Associations/ClassMethods.html#M000530>:clients and a client class declares

hi, let''s take a very simple example. 2 tables: people and phones One person has_many :phones One phone belongs_to :person (the phone table contains a person_id) i began with the classical scaffold generator for the main form (the people form).... How can i add a phone , associated to the NOT YET SAVED person objet , with an ajax mean? do i have to put the unsaved person in session

I''m willing to write a patch for this issue: https://github.com/rails/rails/issues/8893 But want to confirm that the new behavior makes sense before I make the effort. Essentially if you have an unsaved parent and child, and the parent''s association to the child has an inverse_of declared on it. When the parent gets saved, it updates the foreign key on the child, and this

I have two tables: class PgmUpdate < ActiveRecord::Base has_many :pgm_visits, :foreign_key => ''pgm_update_fk'' ... and class PgmVisit < ActiveRecord::Base belongs_to :pgm_update, :foreign_key => ''pgm_update_fk'', :dependent => true ... According to the has_many docs (http://api.rubyonrails.org/classes/

Hi all, Here''s what I am trying to do. I need autocomplete text field in a form. There are 10,000 names to choose from. But when selected I don''t want the string to be saved but the :id attribute of the model. How can I show the string in the text_field and then swap it out for the :id before a create or update. I see that the customized version on scrip.aculo.us has both name

Greetings, I've a need to run 2 instances on one box. I've spent the better part of 2 days looking for docs and howto's and reading the FM. However, I think I'm making too much out of it, thinking that there is more to it than there really is. the first instance is to serve the users, the second instance is for the backup system. I'm running fedora core 2 with samba

Hi, I just generated a scaffold for some existing models I have, and everything is working fine, except I get a 0 error message on the edit view: -------- 0 errors prohibited this statistic type from being saved There were problems with the following fields: -------- I would have thought the default behaviour would be to hide this error message if there are no errors, and that is my impression

Hello, I''m not able to get Errors object when saving some Model instance in ActionWebService::Base subclass. I want to create API method that will return ID of the object when saved successfully. When validation fails and the object is not saved I''d like the method to return ID, as well as the array of ValidationError custom struct. But I cannot fill in this because unsaved

I?m running a model on animal behavior in response to shipping. In most cases, there is only one ship in the study area at one time. Ship length, distance from the animals, speed, angle from animals, and ship direction (as east/west bound) are among shipping-related covariates (with multiple interactions). The tricky part is that sometimes there are 2 ships in the area. I could add all the same

So I''m updating multiple model objects in one go with something like this in my controller: => Photo.update(params[:photo].keys, params[:photo].values) When the update fails due to validation errors, how do I detect it? The Rails API says: "If the save fails under validations, the unsaved object is still returned." So I can''t simply do this: => if

I have a situation where I want to edit an arbitrary number of instances of one model on one page. I can and have accomplished this by manually managing the object <-> text field relationship, but in a way I consider at best hackish. I''d like to know a clean way to do this. If you want to edit the name attribute on a person class, you write code like this

Sorry, that name is a misnomer. However, I was excited to find that Ruby has a built in Observable module and I''m pretty bored, so I apologize in advance.... require ''observer'' # one who is observed class Celebrity include Observable attr_accessor :name attr_reader :is def is=(val) @is = val changed notify_observers(self) end end # one who

Is there any way to validate a form that isn''t connected to a model. I have a form that connects to a controller action and I want to validate the inputs on the form like I would with the validates_ATTRIBUTE_of property on a model. Is there any way to do this? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Reviving an old thread. I haven't noticed this be a problem for a while when saving RDS's which is great. However, I noticed the problem again when saving `qs` files (https://github.com/traversc/qs) which is an RDS replacement with a fast serialization / compression system. I'd like to get an idea of what change was made within R to address this issue for `saveRDS`. My thought is that

Hi -- I have setup a fairly simple Rails site. It uses a layout and 4 clustered instances of Mongrel running on ports 8001 through 8004. The instance of Mongrel running on port 8001 seems to work perfectly. For some reason, the other 3 instances Mongrel are behaving as though they don''t see the layout. Does anyone know why that is; and, more importantly, what to do about it? Thanks.
