similar to: How do you detect if ''update'' save fails?

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

Hi, I''m new to ruby and rails. I just created a simple update page and the update works fine if all form fields are filled in. However there is one field that should never be allowed to be blank. So I put this in my model: class Topic < ActiveRecord::Base validates_presence_of :dr_title validates_length_of :dr_title, :minimum => 1 So, when I submit the form with a blank

Hi, It seems that the validate method in ActiveRecord is not call when doing an myActiveRecordObject.update, right ? So, I call the save method instead, and the validation happens... some has an explanation ? thanks arnaud

Hello all, Is there a method for updating all the attributes from a hash without saving to the database? (the counterpart of update_attributes but without saving). What I want to do is: person = Person.find(params[:id]) person.update_without_saving(params[:person]) #update the in-memory object. # Process person object ....... person.save I know that when you are creating a new object, you can

Hi all, Is there a way to invoke validations at times other than save, create and update? I know that I can do this by writing my own validation checks using errors.add_[blah], but I''d like to leverage the existing validation code. What I have is two sets of fields in a record, set A and set B. Both sets must be validated on record create. However, the trouble is that after

Hi, I''d like to upcase a variable before it is saved, but I''m not sure how to access the incoming param or where this work should be performed: In my update method, I have: @device = Device.find(params[:id]) params[:device[macaddress]].upcase <-- problem code if @device.update_attributes(params[:device]) ....usual stuff here ''macaddress'' is the

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

There´s already a new version of the acts_as_taggable mixin available and look what it is capable of now: # Gets the top 10 tags for all photos Photo.tags_count :limit => 10 # => { ''beer'' => 68, ''wine'' => 37, ''vodka'' => ''22'', ... } # Gets the tags count that are greater than 30 Photo.tags_count :count =>

I saw a Flash-based photo-flipper on TagWorld ( http://www.tagworld.com/thepostalservice) and thought it would be nice to do something similar in Scripaculous. Anyone interested in taking a shot at it? Since rotation isn''t supported in CSS, what I would imagine would be a z-ordered "stack" of DIVs, possibly of slightly different sizes or just x/y-offset a bit from each other.

Hi ! I have the following: <li id="photo_<%= @photo.id %>" class="photo"> <%= link_to(image_tag(url_for_file_column(:photo, :picture)), {:action => ''photo'', :id => @photo}, {:title => @photo.description}) %> </li> <script type="text/javascript" language="JavaScript"><!--

Hello ~ I have RMagick and file_column working in RoR. In my model I am setting up some standard sizes for the submitted photos. The photo files are created and named correctly, but the sizes are wrong. Only the second argument of my geometry call is used, with the width dimension being resized proportionately. file_column :image, :magick => { :versions => { "medium" =>

I used scaffolding, then modified. As an after thought I added a "boolean" checkbox to my database, form with this tag <p> <%= check_box ''is_hot_item'', @photo.is_hot_item %> <label for="is_hot_item">hot item?</label><br> </p> I check it and save. But I don''t get 1 saved in my database field. :( I have just the

I''m using the date_select form helper for a date_of_birth field on an ActiveRecord object. When I try to save a date earlier than 1 Jan 1970, ActionController punts with ActiveRecord::MultiparameterAssignmentErrors. The message it gives is "1 error(s) on assignment of multiparameter attributes". I was able to catch the exception and look at it, and it is certainly complaining

ok so datetime_select if you use the discard options say { :discard_month => true } when you just do update_attributes on said object year would be correct month would be the hour date would be the minute so if you select year: 2005 hour: 12 minute: 13 the time object would go into the db as: ''2005-12-13 00:00:00'' so my question is how do i get the time object properly

first off, thanks (a lot!) sebastian for creating this module... I''ve been spending a lot of time in getting file uploads to work. inside a project I''m working on, I''ve got two different models using it... with one of them it''s working just fine. with another, everything works, with the exception of the url_for_file_column helper, which shows

Ahoy, So i''ve installed the acts_as_taggable module and everything is fine, but i''m a bit confused about this bit of code described in the API "photo = Photo.new # splits and adds to the tags collection photo.tag "wine beer alcohol" # don''t need to split since it''s an array, but replaces the tags collection # trailing and leading
