Summarized Video Transcript

Part 3 will teach you how to build a relational form, with a one-to-many relationship, to set up a full-on database application. Here’s a demo of the form.

After inputting some sample data pertaining to a service request and hitting Submit, a Request ID will be passed to the next page.

That same Request ID will be used when assigning tasks. For example:

  • Assign this request to John Doe by selecting his name on the dropdown list.
  • Add “fix blinds” in the Comments field.
  • Input any future date in the Resolve by field.
  • Click the Add button to create the task.

It’s also possible to add multiple tasks and submit them under the same request. In this case: we can assign a new task to Raj Singh, input “order blinds” in Comments, input another date in Resolve by, then click Add. We can always go back to page one if we want to submit a new request.

This is a simple one-to-many relationship where we can track and see all the tasks pertaining to a single request. In this video, we’re going to show you how to create that relationship between the two tables.

Creating Your Database Tables

If you’ve seen the first two videos, you already understand the process of building an application in Caspio — first, log into your account and click the New App link on top.  You’ll then be given two ways on how to begin:

  1. By importing your existing data
  2. With a blank app

Click the second option to build your application from scratch.

You’ll then be prompted to name your app — input Relational Form and click Finish to see your app listed on your Home screen.

Next, click the Open link of your new app to access its App Overview. You’ll find all the necessary objects to create an app on the left-hand panel.

The most important thing you should build first is your database table.

Tables are the foundation or backbone of any app you develop. For this use case, you’ll be creating four:

  1. A table that will store every request.
  2. A table that will store all the tasks.
  3. A lookup table for categories.
  4. A lookup table for locations.

Begin by clicking the Tables object on the left-hand panel.

TABLE 1: uvg_requests

Click the New Table link on top and list the following fields with their corresponding DataType:

  1. Request_ID – Select Random_ID as the DataType.
  2. Category – Select Text (255) as the DataType.
  3. Location – Select Text (255) as the DataType.
  4. Full_Desc – Select Text (64000) as the DataType.
  5. Access_Instructions – Select Text (255) as the DataType.
  6. Permission_to_Enter – Select Text (255) as the DataType.
  7. Attachment – Select File as the DataType.
  8. Request Status – Select Text (255) as the DataType.
  9. Date_Submitted – Select Timestamp as the DataType.
  10. Date_Updated – Select Timestamp as the DataType. Then under Options to the right, enable Stamp On Update and disable Stamp On Insert.

Take note of the following with regards to the data types used:

  • Use Random_ID, or other ID data types, to uniquely identify each record inside the table.
  • Use Text (255) when storing a maximum of 255 characters in a field.
  • Use Text (64000) when you need users to input up to 64,000 characters.
  • Use File when you need to attach an image, PDF, word document or any other file type.
  • Use Timestamp to automatically record the date and time of form submission.

Click Save on top and name your table uvg_requests, then click Finish.

TABLE 2: uvg_tasks

Click the New Table link on top and list the following fields with their corresponding DataType:

  1. Task_ID – Select Random_ID as the DataType.
  2. Request_ID – Select Text (255) as the DataType.
  3. Assign_to – Select Text (255) as the DataType.
  4. Comments – Select Text (64000) as the DataType.
  5. Resolve_by – Select Date/Time as the DataType.

Note that the Request_ID field in this table functions as a foreign key. Associating it with the primary request ID field from TABLE 1 will establish a relationship.

Click Save on top and name your table uvg_tasks, then click Finish.

TABLE 3: uvg_categories_lookup

Your last two tables will function as data sources for dropdowns on the submission form. Follow the steps below to build your first lookup table:

  1. Click the New Table link on top.
  2. In the Name field, input Category.
  3. For its DataType, select Text (255).
  4. Click Save on top.
  5. Name your table uvg_categories_lookup.
  6. Click Open on the new table container.
  7. List the following values under Category to serve as dropdown menu options:
    • Blinds
    • Electrical
    • Plumbing
    • Parking
    • Pest Control

TABLE 4: uvg_locations_lookup

Go back out to the Tables menu and build your last lookup table. Follow the steps below:

  1. Click the New Table link on top.
  2. For the Name field, input Location.
  3. For the DataType, select Text (255).
  4. Click Save on top and name your table uvg_locations_lookup.
  5. Click Open on the new table container.
  6. List the following values under Category to serve as dropdown menu options:
    • Living Room
    • Master Bedroom
    • Bathroom
    • Laundry Room
    • Balcony

Go back out to the Tables menu to find all your tables listed.

Implementing Table Relationships

Caspio also allows access to your table relationships. Click the Relationship link on top to make changes.

Follow the steps below to implement a one-to-many relationship between TABLE 1 and TABLE 2:

  1. In the list of Tables on the left, check the boxes for uvg_requests and uvg_tasks.
  2. Select your primary key from the requests table (Request_ID field of uvg_requests), then drag the line to the field you are stamping the ID on (Request ID field of uvg_tasks).
  3. In the resulting pop-up screen, Caspio will identify the table relationship you’ve created as one-to-many. No additional changes are needed here so click Create.

A single request can now be linked to many tasks. This, in a database environment, is referred to as a one-to-many relationship, where one item from the parent table can be linked to many items in the child table.

Building Your Request Form

Go to DataPages on the left-hand panel and click the New DataPage link on top. This will open Caspio’s point-and-click DataPage wizard to help you build your app interfaces.

Upon submitting your request form, you’re passing the request ID to this webpage. That is why you’re able to filter details and assign tasks pertaining to a specific request.

To verify if the assigned tasks belong to the right request, view your request table (uvg_requests) and compare the request ID to the one stamped in your task table (uvg_tasks). You’ll find that both IDs are the same. You now understand why this is a one-to-many relationship — one request has multiple tasks.
