Instance Method Detail
Delete the model by building and executing a DELETE
query.
A deleted model is not persisted anymore, and can be saved again.
Clear will do INSERT
instead of UPDATE
then
Return true
if the model has been successfully deleted, and false
otherwise.
Save the model. If the model is already persisted, will call UPDATE
query.
If the model is not persisted, will call INSERT
Optionally, you can pass a Proc
to refine the INSERT
with on conflict
resolution functions.
Return false
if the model cannot be saved (validation issue)
Return true
if the model has been correctly saved.
Example:
u = User.new
if u.save
puts "User correctly saved !"
else
puts "There was a problem during save: "
# do something with `u.errors`
end
on_conflict
optional parameter
Example:
u = User.new id: 123, email: "[email protected]"
u.save(-> (qry) { qry.on_conflict.do_update { |u| u.set(email: "[email protected]") } #update
# IMPORTANT NOTICE: user may not be saved, but will be still detected as persisted !
You may want to use a block for on_conflict
optional parameter:
u = User.new id: 123, email: "[email protected]"
u.save do |qry|
qry.on_conflict.do_update { |u| u.set(email: "[email protected]")
end
Performs #save
call, but instead of returning false
if validation failed,
raise Clear::Model::InvalidError
exception
Pass the on_conflict
optional parameter via block.
