Instance Method Details

#location ⇒ Object

this has to be resolved from amongst all the options in the specification. it has an order of preference like : if location ids are selected, then return those if within radius is specified, then alongwith it origin_location should also be specified, and if location_categories are specified, then they should also be added to the hash.

#origin_location ⇒ Object

usually this is the location of the user it is a hash of type: {:lat => ,:lng => }

# File 'app/models/auth/workflow/specification.rb', line 36

field :origin_location, type: Hash

#permitted_location_categories ⇒ Object

what location categories are permitted.

# File 'app/models/auth/workflow/specification.rb', line 28

field :permitted_location_categories, type: Array, default: []

#permitted_start_time_ranges ⇒ Object

this is an array of specification arrays. like : [[yy,mm,dd,number of seconds since midnight,number of seconds since midnight + some seconds],,[]] the user can pick one of them. each element has the following elements: 0 -> year specification 1 -> month specification 2 -> day_of_month (1-31 : representing the dates) 3 -> day_of_week (0->6 : representing monday -> sunday) 4 -> seconds since midnight, minimum time after midnight at which this step can be started to be performed. 5 -> how many seconds to add to the [4] to get the maximum time after midnight at which the step can be started. This can be any value, implying that the step can be started on some subsequent day , relative to this day. these time specifications are added directly to the step that they refer to. so we call get nearest instant here itself.



21
 
# File 'app/models/auth/workflow/specification.rb', line 21

field :permitted_start_time_ranges, type: Array

#permitted_within_radius ⇒ Object

has two elements, each can be a maximum and minimum within radius.



39
 
# File 'app/models/auth/workflow/specification.rb', line 39

field :permitted_within_radius, type: Array

#selected_location_categories ⇒ Object

which one is selected by the user. should validate this as being one of the permitted location categories.



32
 
# File 'app/models/auth/workflow/specification.rb', line 32

field :selected_location_categories, type: Array

#selected_start_time_range ⇒ Object

the index of the chosen specification from amongst the permitted_start_time_ranges and actual will be got based on that.



25
 
# File 'app/models/auth/workflow/specification.rb', line 25

field :selected_start_time_range, type: Array

#selected_within_radius ⇒ Object

has to lie in between the maximum and minimum limits.

# File 'app/models/auth/workflow/specification.rb', line 42

field :selected_within_radius, type: Float

#start_time_range(current_time) ⇒ Object
