In R-devel (svn 49628) and back to at least R 2.7.0 we get inconsistent results when attempting to attach attributes to a variable with the value NULL.

Hi, I''ve started looking at ticket 90<http://merb.devjavu.com/projects/merb/ticket/90>and there are a couple of situations that the current implementation doesn''t cater for. 1. Tag Attributes are wiped out. - <tag1 attr1=''1''>Content</tag1> #=> { "tag1" => "Content" } - I think it should return - {"tag1" => { "attr1" => ''1'', "__content__" => "Content" } 2. Mixed content can throw an...

Ok, So, I''ve got two data tables associated through a foreign key. class Child < ActiveRecord::Base belongs_to :parent, :class => Parent, :foreign_key => "parent_id" # also has attr1, attr2 end class Parent < ActiveRecord::Base has_many :children, :class => Child, :foreign_key => "parent_id" end So, I''m trying to build the new/edit form for the child table... Basically, I was aiming for something like: <%= text_field "child", &quot...

I find myself writing the following frequently: r = MyActiveRecord.where(:attr1 => cond1, :attr2 => cond2, ...) r.exists? ? r.first : r.create ... which has the effect of returning an instance of MyActiveRecord if all the conditions are met, or creating one if it doesn''t. A variant of this: c = MyActiveRecord.new(:attr1 => val1, :attr2 => val2,...

Thanks for your feedback David.... Yes, the intention is to support duck-typing. In my code example, a.attrB1 = 5 .... is probably more accurately stated as ..... a. attr1.attrB1 = 5 Certainly this would be an unsafe call because we would not know that attrB1 is an attribute of attr1 until runtime. I believe this type of call is valid in a language like Python. Are there any references out there that would help me implement something like this? thanks, frank...

I think I might solve the problem by appending a "[data]" to every key of the object.attrib...

All, My apologies if this is a little long-winded and stream of consciousness-y :). SUMMARY: Why do we extend ActiveRecord instead of mixing it in to our model classes? Been thinking about my app''s models and starting to want to build something of a hierarchy. I have some commonality across 3 of my model classes and I''d liek to aggregate the behavior in a superclass.

Hi, i have a "place" model with 2 columns (id, name). I''m calling an external api which gives me data to create a new place object. I would like to add the address from the external place to the place object and render it as a json result, without storing it in the database. i don''t get any errors, but the address never shows up within the json output. i''ve

Hello, Arel::SelectManager (arel 2.0.9) uses following statement to insert a new record: @engine.connection.insert im.to_sql, ''AREL'', primary_key_name, primary_key_value But in DatabaseStatements insert ist defined as: insert(sql, name = nil, pk = nil, id_value = nil, sequence_name = nil) Actually, Arel::SelectManager does not use the sequence name.
