Migration files will import this from django.db.migrations.Migration and subclass it as a class called Migration. It will have one or more of the following attributes: - operations: A list of Operation instances, probably from django.db.migrations.operations - dependencies: A list of tuples of (app_path, migration_name) - run_before: A list of tuples of (app_path, migration_name) - replaces: A list of migration_names Note that all migrations come out of migrations and into the Loader or Graph as instances, having been initialized with their app label and name. cCsj||_||_t|jjƒ|_t|jjƒ|_t|jjƒ|_t|jjƒ|_dS(N(tnamet app_labeltlistt __class__t operationst dependenciest run_beforetreplaces(tselfRR((sl/var/www/html/phendo-backend/phendo_python/env/lib/python2.7/site-packages/django/db/migrations/migration.pyt__init__3s   cCs5t|tƒstS|j|jko4|j|jkS(N(t isinstanceRtFalseRR(R tother((sl/var/www/html/phendo-backend/phendo_python/env/lib/python2.7/site-packages/django/db/migrations/migration.pyt__eq__<scCs ||k S(N((R R((sl/var/www/html/phendo-backend/phendo_python/env/lib/python2.7/site-packages/django/db/migrations/migration.pyt__ne__AscCsd|j|jfS(Nu(RR(R ((sl/var/www/html/phendo-backend/phendo_python/env/lib/python2.7/site-packages/django/db/migrations/migration.pyt__repr__DscCsd|j|jfS(Nu%s.%s(RR(R ((sl/var/www/html/phendo-backend/phendo_python/env/lib/python2.7/site-packages/django/db/migrations/migration.pyt__str__GscCstd|j|jfƒS(Nu%s.%s(thashRR(R ((sl/var/www/html/phendo-backend/phendo_python/env/lib/python2.7/site-packages/django/db/migrations/migration.pyt__hash__JscCsF|}|r|jƒ}nx$|jD]}|j|j|ƒq%W|S(u× Takes a ProjectState and returns a new one with the migration's operations applied to it.
