similar to: Update_attributes working, or not? I can''t tell.

Hello again... so I narrowed my problem down. For some reason, while using login_generator, any User object I pull from the DB can be updated one attribute at a time using update_attribute, but when I try and do update_attributes it fails every time. Is this a limitation with login_generator that I don''t know about, or is there a way around this? I also tried the .update method and

I dont know if its me or the dodgy win-32 intall of ruby/mysql, but I can''t seem to get update_attributes to work. In my user controller, I have: def update @user = User.find(@params[''user'']["id"]) if @user.update_attributes(@params["user"]) flash["success"] = "Updated Successfully" redirect_to :action =>

In my User model, I had this: def update_last_login_time self.last_login = Time.now self.save end But last_login was not being set. When I changed it to this it worked: self.update_attribute( :last_login, Time.now ) Any ideas why? ~S

Just in case it saves someone else the several hours of insanity I just went through, update_attributes will not save unless the model validations are satisfied, but update_attribute (the singular form) will save the attribute to the database even if the model validations would fail! This appears to be a feature, not a bug (http://api.rubyonrails.com/classes/ActiveRecord/Base.html) although

If I am changing a boolean value, no matter what approach I take, I get the same results: lets say table "users" has an "enabled" field that is boolean: user = User.find(1) user.enabled.toggle NoMethodError: undefined method `toggle'' for false:FalseClass user = User.find(1) toggle(user.enabled) NoMethodError: undefined method `toggle'' for

Does anyone know of a way to update individual attributes with validation? update_attribute disables the validation checks in the record model, so I''m wondering if there''s a workaround for this. In my application, I want to allow the user to update some or all the attributes without having to enter :password and :password_confirmation, both of which are subject to

Hi! I have updated my app to rails 2.3. I have form that has few nested models and I am happy that I can just write accepts_nested_attributes_for :tasks, :allow_destroy => true, but update_attributes! does not update my nested model. I have tried update_attributes, and it works. Any ideas? Few lines from log: update_attributes: SQL (0.1ms) BEGIN Education Update (0.3ms) UPDATE

I am trying to wrap the updating of two models in a transaction and when the transaction fails it is not rolling back. My method is : def update_attributes(user,params) @user = user @company = user.company begin User.transaction do @user.update_attributes!(params[:user]) @company.update_attributes!(params[:company]) end true rescue false

I notice that ActiveRecord::Base.update_attributes() calls save(). What if I want to get an exception if the save fails? Is there a way to get the update_attributes() function plus the save! function? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

I know the debate of whether this should validate has been rehashed many times. My question is, what are the consequences of overriding this method to force validation? Will this break fundamental things? Will it break plugins? Is there a reason not to have a strict validation option? In my code I will never use this as I consider it a terribly broken method, but some gems use it and in one case

Hi, IN one of my unit tests I get an ActiveRecord::StaleObjectError: Attempted to update a stale object object.save! in object I have apart from other stuff an after_save method, which calls object.assosication.update_attributes(...) If I remove that line from my code my tests succeeds. Unfortunetly, I do not understand why an update_attributes call can generate an StaleObjectError. Maybe

Hope someone can tell me what''s up, because this has me baffled. I have an Image model, and a Provider model. Both are defined as "has_and_belongs_to_many" relating to each other. In my image form partial, I have a bit of AJAX generating the provider_ids array dynamically from a provider AJAX search on the same page. So for example, each time I click on a provider name that

Hi, I am facing a problem while trying to test a method that updates an attribute. The attribute format should be converted to YAML format before storing in the table which is excatly what is going on. But when testing it using expectations in rspec it returns an error. *** below is the error message : Spec::Mocks::MockExpectationError in ''InteractController (submit) - saving a form to

Hi all, I''ve searched the forumns, but I can''t seem to find an answer to this one. I''m having trouble getting optimistic locking (OL) to work in my app, even though all of the pieces are there: * table has lock_version column, with default of 0 (zero) * lock_version column is being incremented by the first update (but the second doesn''t catch it) *

I''m having problems in a controller i am writing. i get this exception: wrong number of arguments (1 for 0) ## this does not work: @voicemail_user = VoicemailUser.find(session[:asterisk][:user_id]) if (@voicemail_user.password == params[:pwd][:current]) @voicemail_user.update_attributes({"password" => params[:pwd][:newpwd2]}) end ## but this works:

I''m working on a form that updates a product record and several associated detail records. The detail records are showing and populating okay in the form. But when it hits the controller, I get Couldn''t find Detail with ID=detail AND (details.product_id = 38). The :detail params seem to refer to the correct record id. Anyone have an idea how to fix this? Here''s the

It seems that attachment_fu is a pretty popular plugin (it''s great), but I''ve been having a terrible time trying to figure out an issue when using "update_attributes". I''m storing files on the file system rather than in a database. It seems that when "update_attributes" is called with a new file, upload_data= tries to copy a file that

My application is so far mostly built from scaffold. When I edit an existing record (I''ve turned off validation) the update method is called. I get this error: NoMethodError in <module>/<controller>#update You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occured while evaluating nil.+ I get the same error when

Is it possible to update the parameters from a form without saving? @model.update_attributes(params[:model]) will save the model after updating its attributes. I''d just like the attributes updating without a save. Thanks Chris -- Posted via http://www.ruby-forum.com/.

Hi, I have one method, ''updateStuff'', that will call ''update_attributes'' on 3 different models in the DB..... How can I account for validation to revert back all updates if one of the models is not valid? I''ve looked into Model.valid? which doesn''t seem to work for me .. Any idea? Thanks
