Public Instance methods

forme_input(_form, field, _opts)

Keep track of the inputs used.

37   frozen? ? super : (forme_inputs[field] = super)
38 end
forme_inputs()

Hash with column name symbol keys and Forme::SequelInput values

forme_parse(params)

Given the hash of submitted parameters, return a hash containing information on how to set values in the model based on the inputs used on the related form. Currently, the hash contains the following information:

:values

A hash of values that can be used to update the model, suitable for passing to Sequel::Model#set.

:validations

A hash of values suitable for merging into forme_validations. Used to check that the submitted values for associated objects match one of the options for the input in the form.

49   hash = {}

53   forme_inputs.each do |field, input|
54     next unless column = forme_column_for_input(input)
55     hash_values[column] = params[column] || params[column.to_s]
56 
57     next unless validation = forme_validation_for_input(field, input)
58     validations[column] = validation
59   end
60 
61   hash
62 end
forme_set(params)

Set the values in the object based on the parameters parsed from the form, and add validations based on the form to ensure that associated objects match form values.

   # File lib/sequel/plugins/forme_set.rb
66 def forme_set(params)
67   hash = forme_parse(params)
68   set(hash[:values])
69   unless hash[:validations].empty?
70     forme_validations.merge!(hash[:validations])
71   end
72   nil
73 end
forme_validations()

Hash with column name symbol keys and [subset, allowed_values] values. subset is a boolean flag, if true, the uploaded values should be a subset of the allowed values, otherwise, there should be a single uploaded value that is a member of the allowed values.

30 def forme_validations
31   return (@forme_validations || {}) if frozen?
32   @forme_validations ||= {}
33 end
validate()

Check associated values to ensure they match one of options in the form.
