i new rails , try find validation method corresponding validate presence of attribute when updating record. if attribute not present, meaning attribute not exist request body, rails should not update record. validates :description, presence: true and validates_presence_of :description doesn't seem job. there method purpose? seems quite common in every day scenarios. if say: model.update(hash_that_has_no_description_key) then you're not touching :description : sending hash without :description key update not same sending in hash :description => nil . if model valid (i.e. has description) update won't invalidate because won't touch :description . you this: if attribute not present, meaning attribute not exist request body, rails should not update record. since you're talking request body (which models shouldn't know about) should dealing logic in controller prepares incoming data update call. you check in controller , ...
