I a have the following datamapper ressource :
class Job
include DataMapper::Resource
storage_names[:default] = 'job'
property :id, Serial
property :at, Integer, :required => true, :min => 0
property :name, Float, :required => true, :default => 0
property :cpu, Float, :required => true, :default => 0
property :memory, Float, :required => true, :default => 0
end
When do :
DataMapper.auto_migrate!
The table 'job' is correctly created in the database. But when I do :
Job.create(
:at => entry[:timestamp],
:name => process.to_s,
:cpu => data[0],
:memory => data[1]
)
Nothing is really inserte开发者_JAVA技巧d in the 'job' database table. (Nothing in datamapper log too)
Any idea ?
Try enabling dm-validations and checking #errors
in the returned object, this will tell you if there are any problems with the data. If its invalid, DataMapper won't insert anything.
Try Job.save
after your Job.Create
:)
The error was :
property :name, Float, :required => true, :default => 0
and
:name => process.to_s,
float <-> String
thats why datamapper don't insert the object database.
Thanks all for your helps.
