What''s the recommended way to catch errors like this: NoMethodError in Register#confirm Showing app/views/register/confirm.rhtml where line #4 raised: undefined method `namen'' for nil:NilClass I get this error when someone does somethinh like: http://.........../register/confirm?email=jkdsfadslkjflksd If I make: remail = params[:email] @user = Request.find(:first,

I tend to allow nulls in cases where the value is unknown, even if it''s a text/varchar field. RoR seems to push empty strings into these fields. Is there any way to get RoR to use NULL vice '''' if the input box is empty? Thanks! - Ian

Hi, I am trying to validate a numeric value passed in from a form, which is saved in a MySQL db as decimal(9,2) Now problem is I need to ensure people don''t enter a form value like -. 003. In my validations, I have a validates_numericality_of check being done. Furthermore, in validate method, I have a check using an if statement such as : ((an_object[n].nil? or an_object[n] < 0) and

There''s a small inconsistency in ActiveRecord''s callback syntax that has tripped me up before. It wouldn''t be a big deal, but it can lead to a silent failure. I''d like to suggest that it either be made consistent or be made to fail loudly. The issue is that to do something before validating, but only when creating, you use `before_validation on: :create`,

In ActiveRecord''s callbacks, methods within a before_create callback are called after the validation, but before the model is created. This was an intentional design decision, but I think it was the wrong one. What do you think? When I think of before_create, I think of before_validation :foo, :on => :create, but, by default, before_create is synonymous with after_validation :foo,

Hi all, For various reasons I need to have foreign keys with not null constraints. Eg: create_table :people do |t| t.column :name, :string t.column :household_id, :integer, :null => false end create_table :households do |t| t.column :name, :string end add_foreign_key_constraint :people, :household_id, :households, :id So the people table has a foreign key into

Hi all, I''ve got a form which accepts a "price" field and I''m attempting to validate it and allow some flexibility in the way the user enters it. It''s a numeric field but I want the user to be able to enter dollar signs and commas naturally in the data entry. I''m trying to understand how to use validates_format_of, and I''m not sure what

Hi all My visitors can create party organisator profiles, and I want assign them as the creators (the field creator_id in the organisators table references a member in the members table). To do that I tried it with before_validation: def before_validation creator = Member.find 1 end Sadly, this does not work. The validation validates_presence_of :creator_id Still tells me, that

Hi, I was looking around a bit and couldn''t find any callbacks that executed before before_validation The current problem with using before_validation is that it won''t fire if I''m not using validations with #save(:validate => false) - which makes sense. Before_save won''t suffice because I want these callbacks to fire before validation on the occasions that

Hi all. I usally make backups of databases mysql. I make buckups of all datbase for example: mysqldump -u user -ppassword name_db > backups.sql also I make backups just its schema for example mysqldump -u user -ppassword name_db --no-data > backups.sql but now I need a backups incrementals, because the size of DB is very big (500 mb) How to make this? regards -- *Atte.

Hi, I often find myself using bits of code like this inside ActiveRecord, perhaps it''s useful for others, or others can improve on it: ########### # fix user input before validating it before_validation :sanitize_input # santize input before actual validation is called # this uses the little methods defined below def sanitize_input trim %w(adres postcode woonplaats email naam

I want to remove the leading and training spaces for most of the resources in my rails application For a new POST request, rails does the xml parsing and passes the params hash to the controller. Some of the parameters have leading and/or trailing whitespaces which are causing problems (e.g. new resources being created rather than using the old ones). I don''t want to put the code in all

Before I head down the path of converting voicemail to an ODBC backend, I have a couple questions that I was hoping someone would know. 1. Is the voicemail message stored in the datbase, or just it's location/filename? 2. Does MWI propagate when using an ODBC backend? 3. If it does both of those things, wouldn't it work well for a centralized voicemail system instead of a solution like

Hi All, Is there a way to filter / modify the output of a model class before it''s returned to controller/view that''s calling it? Example: I have a field phone_number which I always want to preformat using the number_to_phone() helper.... Any help is appriciated. Thanks! -- Posted via http://www.ruby-forum.com/.

Hi all, Short of hacking the code apart, is there a method making the login_engine authenticate against email address rather than username? I find that people rarely remember usernames, and would prefer to use email addresses as the identifier. Thanks! Tom

Hello, I''m trying to build an app (mysuperapp.com) that allows users to create an account in which a default subdomain (IE: joeshmoe.mysuperapp.com) will be created as their homepage. In their profile settings, I also want to give them the ability to add their own domain name so their homepage now can be joeshmoe.com. I know this is possible in rails w/ plugins like subdomainfu

I have validates_uniqueness_of on one of my model''s attributes. I''d like to make it so that I can set the attribute to something, and if it clashes with an existing record, automatically append a number to it. I''m not really sure of the best way to go about this - any recommendations? Pat

who can explain this to me? def before_validation logger.info url url = "http://" << url if url[0..3]=="www." end the logger line correctly logs any URL that''s been submitted, let''s say it''s "www.amazon.co.uk" BUT Rails raises an exception on the next line, complaining about nil. [] (obviously from the url[0..3] bit) It works
