Request validator is a gem thats allows you do run validation in your controller rather than your models. Why do you need validates :question, presence: true in model when v.check('param').notEmpty() solves it
No dependency!
$ gem install request_validatorConfiguration
Validator.configure do |config|
config.skip_main_object_empty = true
config.error_mode = 'surpressed'
end
Dillinger is currently extended with the following plugins. Instructions on how to use them in your own application are linked below.
| Option | Description |
|---|---|
| skip_main_object_empty | Allows your to skip error when the main object is empty. Default is false |
| error_mode | silences errors and move on to next step |
This gem can be used in two ways and both returns same response in same format.
We will be using this params throughout
{
"name": "User 1",
"phone": "789",
"role" : "admin",
"email": "will@mail.com",
"website": "https://google.com",
"actions": ["jsjjd","skskjd"],
}
The first method allows you to match params to methods without explicitly specifying the methods.
Validator.new.validate(params, {
'name' => 'string',
'phone' => 'number',
'email' => 'email',
})
If thers are any errors, response object containing property error as an array containing the error messages is returned
It skips other params if they are not specified...
Example
v = Validator.new(params)
v.check('email').notEmpty().isEmail()
v.check('name').isString().notEmpty()
v.check('role').isIn(['admin', 'user']).notEmpty()
v.check('actions').isArray()
v.check('website').validUrl()
v.result()
Using this method, it allows changing of methods together. The method check must be specified a parameter is passed into it which is the property to check for.
The params body must me passed into the new method of the validator.
Example response
{
"error": [
"phone is not a valid number"
]
}
- Write tests (but its working right now)
- Include more methods
