# Plan an Adalo app with Codex before building the screens

## Short answer

Give Codex one user journey and ask for an Adalo build specification: collections, relationships, screen data, actions, access rules, and acceptance checks. Build that path in your editor, then return the actual configuration to Codex for review.

## Intended outcome

A small, reviewable build plan for a repair-request app, with enough detail to connect the first list, detail screen, and create action.

Use Codex to make the build decisions visible before placing components. This repair-request example turns one user journey into a model you can implement, inspect, and revise as the app grows.

## Requirements

- A Codex workspace where you can keep the app brief and build notes
- An Adalo account and confirmation of whether you use the visual builder or Ada
- One primary user journey and fictional example data
- A decision about who may view, create, edit, and delete each kind of record

## Step by step

1. **Describe one complete job**

   Start with a member reporting a broken item, seeing their own requests, and opening one request to check its status. Leave volunteer scheduling, payments, and messaging out of this first loop. Tell Codex what a successful submission looks like.

2. **Ask for collections and record relationships**

   Have Codex propose Users, Requests, and Request Updates with property types and relationship directions. Separate the submitting member from the assigned volunteer even though both point to Users. Review what an empty volunteer relationship should mean before creating it.

3. **Make access rules explicit**

   Ask for a matrix covering signed-out visitors, the submitting member, an assigned volunteer, and an unrelated member. State each permitted read and write operation. Use it to configure actual data access controls; a list filter only determines what that list displays.

4. **Map the records through the screens**

   For My Requests, Request Detail, and New Request, document the collection queried, the current record, and the action on each button. A tap on a request row must carry that request to its detail screen. A create action must attach the submitting member.

5. **Build with contrasting sample records**

   Create two fictional members and requests with different owners and statuses. Add one unassigned request. In the visual builder, configure the model and actions directly; in Ada, use the reviewed specification to request the corresponding app changes and inspect what it generates.

6. **Return the implementation for review**

   Give Codex the actual field names, relationship settings, action order, and redacted screenshots. Ask it to compare the implementation with the original acceptance checks and name assumptions it cannot confirm. Complete those checks in Adalo before expanding the feature.

## Why it works

- The specification gives every screen a data source and every action a target record. That prevents a plausible screen design from hiding a missing relationship or an ambiguous update.
- Codex is useful for turning a vague brief into explicit decisions. The builder and runtime provide the evidence that those decisions were implemented correctly.

## Example brief to give Codex

I am building a neighborhood repair app in Adalo. A member reports a broken item and tracks its status. A volunteer may later be assigned. For the first version, plan only request creation, a member's own request list, and request details. Produce a collection table with property types and relationship directions, a screen-by-screen data flow, a read/write access matrix, six fictional sample records, and acceptance checks. Use Adalo terminology. Do not assume you can inspect my account. Identify any decision that depends on whether I use the visual builder or Ada. Save the result as a build brief I can revise.

Make the output concrete enough to review. For example, My Requests reads Requests belonging to the signed-in member; Request Detail receives the selected Request; New Request creates a Request with the member relationship populated. If Codex only produces a feature list, ask it to supply these record-level connections.

## The decision that changes the data model

Suppose the repair app later allows a volunteer to post several progress notes. Storing only Latest Update on Requests overwrites the previous message. Request Updates preserves history because each update has its own author, date, and parent request. That distinction comes from the product requirement, rather than from a preference for more collections.

Ask Codex to walk through three example records before accepting the schema. Which member owns the request? Which volunteer is assigned? Who wrote the most recent update? If any answer depends on matching a display name, replace that fragile link with an explicit record relationship.

## Use the plan in either builder

For the visual Adalo builder, use the specification as a checklist while creating collections, choosing relationship directions, adding components, and configuring actions. Keep the real labels in the brief so a later Codex review does not compare two different naming systems.

For an Ada-generated app, its current Database documentation describes schema changes through Ada and access through declared endpoints. Give Ada a narrow slice of the specification, inspect the generated collections and endpoints, and compare their scope with your access matrix. Do not transfer older visual-builder menu instructions into that workflow.

## Bring an existing app back into Codex

This workflow also works in reverse. Start with an existing app's collection list, relationship settings, screenshots, and action descriptions. Ask Codex to reconstruct the user journey and explain where the same information is duplicated or a screen relies on an unavailable record. Remove private member details from the material first.

The useful deliverable is a short discrepancy list: the brief expects the submitting member to be saved, the actual create action omits it, and the owner filter consequently matches nothing. That is actionable. A generic instruction to improve the database is not enough to guide a builder change.

## What still needs checking

- Original written example with no accompanying video; the proposed schema and access rules still need implementation and testing in your app.

## Data model

| Collection | Properties | Relationships |
| --- | --- | --- |
| Users | Display name; contact details kept private | One member can submit many Requests; one volunteer can receive many assignments |
| Requests | Title; description; status; created date | Each request has one submitting User and an optional assigned User |
| Request Updates | Message; created date | Each update belongs to one Request and has one author User |

## Common failures

### Codex proposes too many collections

Ask which collection is required for the first user journey. Keep a separate update collection when history matters; defer unrelated features until creating and reopening one request works.

### The detail screen opens without the request

Inspect the row's navigation action and the destination's available record data. Compare the request ID selected on the list with the record shown on the detail screen.

### The owner filter seems to protect private records

Use the access matrix to inspect collection permissions or the relevant Ada endpoint rules. Test access as the unrelated member; hiding a row does not establish a data access boundary.

## Testing checklist

- [ ] A member creates a repair request, opens its detail screen, and sees the same saved record after signing in again.
- [ ] A second member cannot read or change the first member's private request, including by opening its record directly.
- [ ] A request with no assigned volunteer still has a useful detail screen and a clear unassigned state.
- [ ] Two people with the same display name remain distinguishable because relationships use records rather than copied names.
- [ ] Every screen names its incoming record and intended action target
- [ ] Submitting member and assigned volunteer have distinct relationships
- [ ] The actual access rules match the written access matrix
- [ ] The first create, list, and detail journey works with two accounts

## Limitations

- Codex can prepare a build specification from the information you provide; it does not automatically receive access to your Adalo account or builder.
- This is a proposed workflow supported by official documentation, not a hands-on test of the example app.
- The visual builder and Ada-generated apps expose different schema and access controls; confirm which experience your account uses.
