Adding Properties

How to add properties in the model:

1. Once you are in the selected model, click on +Add Property

2. Add the name of the property

3. Select the type of the property. A property can be one of the basic types or a created model. (Example: You want only numbers, name or date and time)

Basic types of properties:

(i) text - it should only be simple text (ii) number - it should be a number (iii) email - it should be in an email ID format (iv) url - it should be in a URL/website format (v) description - when you want to have more text (vi) image - if you want it to add an image (vii) file - if you want to add a file (viii) date - date in dd/mm/yyyy format (ix) time - time in x format (x) datetime - if you want to have both the date and time (xi) any_one_of - when the value of the property has to be from a list of items (xii) many_of - when the value of the property is more than one and a part of a list of items (xiii) color - select a color (xiv) password (xv) boolean - true or false

1. Next, you can assign additional properties to the main property.

Additional properties:

(I) is_many: if multiple values for the same property must be stored Example: If you want to add multiple images a product, you must select the “is many” property.

(II) is_required: if a value is compulsory to create a particular model data. If this property value is undefined, the data will not be created. Example: If you want the name to be mandatory of a product, you must select the “is required” property.

(III) is_unique: a value must be unique across all the data for a particular model. Example: If you want the user's email to be unique and not be repeated in your database, you must select the “is unique” property.

(IV) is_json*: if you want a property to have sub-properties, use “is_json”. How to use is_json: a. When you want to store multiple values of a property in a model, create a new model with those properties b. In the type field select the model you have created as type. Example: Suppose you want to create an application to list down all the car manufacturers/brands, and you want to store all the cars from different brands. So each car will have its own sub-properties like price, colour, type of car and so on, then you must use is_json for the car property under the car manufacturer model.

(V) is_relation*: If data of one model must be linked to another model, a second model must be created, and then the property type of the first model must be set to the second model to create a relation. (Click on the “is_relation” checkbox) Example: if you want to create a social media platform, every post is liked/loved by multiple users, then the type of “liked_by” property of the post has to be “user” type, where “user” is another model and “is_relation” has to be set to true (Click on the “is_relation” checkbox) and “is_many” has to be checked too. *(if type is one of the selected models, this property is shown)

1. Click on the “Add” button and it will add the property that you have created.
