forms - How do I so a select input for a STI column in a Rails model? -
I have a model with a single-table succession on the type column:
class abs & lt; ActiveRecord :: Base type = [dog, cat, hamster] validates_presence_of: name end
I want to provide a This gives me the following error: I read to use the aliases for the field and Neither suggestion worked? Strangely, it works fine on my machine (MRI 1.8.6 on RVM), but fails on platforming server (not MRI 1.8.7 on RVM). The main difference between "Ryan Bates" "suggestion self" (which is about the maximum rail) & lt; select & gt; Pages hanging on new and edit:
& lt;% form_for @model do | F | & Gt%; & Lt;% = f.label: name% & gt; & Lt;% = f.text_input: name% & gt; & Lt;% = f.label: Type% & gt; & Lt;% = f.select: type, pet :: TYPES.map {| T | [T. Haaman_Naw, T.O_s]}%> & Lt;% end% & gt;
ActionView :: TemplateError (wrong logic type string (expected module)) #type , because Ruby assumes that the reserved word which is similar to #class I have tried
class pet & lt; ActiveRecord :: base ... alias_attribute: klass,: type end
class abdomen & lt; ActiveRecord :: Base ... def klass self.type end def klass = (k) self.type = k end end
), And direct access to the property through its implementation suggestion bracket ("[: type] =") is created with your implementation, the method calling ("auto type =")
then try to do something like this:
class pet & lt; ActiveRecord :: Base ... def klass self [: type] end def klass = (k) self [: type] = k end end
