As a visual representation of this, you can see the arrow from the review field to the Review model above.įor information on all the categories and how to pick which one is right for your field, take a look here. This type is called a OneToOneField, because it links one field to another model. A review consists of several pieces of information you need to keep track of, like the title, rating, and description.Īs a result, you have to create a new data model called "Review" and link the review field within the User model to this new data type. While the name, email, and phone number are simple field types like the ones mentioned above, the review field’s type is different. For example, you can create a User model that contains the fields name, email, phone number, and review (shown below). Most of them, like the DecimalField and DateTimeField are self-explanatory, but others like OneToOneField require explanation.Ī OneToOneField is a field that links to another model. For example, if the name of the field is “quantity,” you would want that piece of data to be an integer and not a character or URL.īasic data types include integers, floating point numbers, characters, and booleans, which are respectively listed as IntegerField, FloatField, CharField, and BooleanField on the CB App Builder.Īs shown above, there are a number of other options for field types. Refers to what type of data this field is. Continuing the marketplace example, some fields you would want to keep track of might be a transaction’s total, transaction number, buyer, seller, and date. Field:įields are pieces of data that pertain to a model, or, more simply, characteristics of a model. Generally, each model maps to one database table. Then, each field (defined below) within this transaction model would have pieces of information (data) that you want to know about each transaction in your marketplace. Model:Ī model refers to a grouping of data you want to keep track of, usually stored in a table.įor example, if you are building a marketplace app and you want to know and store information about each transaction that takes place, you could call your model “bill” or “transaction”. How to use the Crowdbotics Model Builder Terminologyīefore proceeding, let's define a few key terms. You don’t need to learn Django and you don’t need to use Firebase. The program on your laptop makes an order through LinkedIn’s API and LinkedIn fulfills the order.Ĭrowdbotics’ new Model Builder makes creating these APIs very simple. So LinkedIn offers an API: a menu for ordering specific stuff. However, it cannot go over to LinkedIn and mess with data there, because just like the restaurant doesn’t want you in the kitchen, LinkedIn doesn’t want your programs in their data. When you have a program on your laptop, it can do a lot of digging around and talking to parts of your laptop. The API takes your order, reports it to the kitchen, and the kitchen makes your food. You can’t get your food until you order, and you have to order through the cashier. Imagine you’re at a fast food restaurant. You might’ve heard of an API before, and it’s important for backends, so here’s what it is and how it works: API stands for Application Programming Interface, and it is a way for information from one program to be shared with other programs. Just as the Crowdbotics Storyboarding Tool helps you lay out your user flow, the Crowdbotics Model Builder is for building backends. The backend is everything going on behind the curtain. The frontend is what the user sees, interacts with, and experiences (buttons, colors, fonts, stuff like that). Getting Started with the Crowdbotics Model BuilderĬreate and edit data models visually with the Model Builder in CrowdboticsĪll apps have a frontend and a backend. What is the Model Builder and what is it for? Crowdbotics models, how to edit, and how to build with the model editor.
