Vuetify Dialogs: Adding Operations

Welcome back to Pantr.io! In our previous session, we successfully implemented the necessary functionalities for our Vue.js application. We achieved reactivity and time travel debugging, allowing us to efficiently manage our data. Now, it’s time to add more useful operations to enhance user interaction and improve the user interface.

Implementing a Dialog Component

To enable users to add new areas and items, we’ll incorporate Vuetify’s Dialog component. This dialog will be opened by clicking a button with a plus sign. Once opened, users can input the name of the area or item and add it to the list.

To start, let’s remove any unnecessary code that we no longer need. We’ll remove the test code and buttons related to areas, leaving us with a clean slate to work with.

Now, we can add the dialog component with the following code snippet:

<v-dialog v-model="dialog" width="500">
  <template v-slot:activator="{ on }">
    <v-btn @click="dialog = true" color="pink" fab dark small>
      <v-icon>mdi-plus</v-icon>
    </v-btn>
  </template>
  <v-card>
    <v-card-title>New Storage Area</v-card-title>
    <v-card-text>
      <v-text-field v-model="areaName" label="Area Name"></v-text-field>
    </v-card-text>
    <v-card-actions>
      <v-spacer></v-spacer>
      <v-btn color="primary" text @click="reset">Cancel</v-btn>
      <v-btn color="primary" text @click="addArea">Add</v-btn>
    </v-card-actions>
  </v-card>
</v-dialog>

Let’s break down the code:

• We use the v-dialog component to wrap the dialog content. The v-model directive binds the visibility of the dialog to the dialog variable, which controls whether the dialog is open or closed.
• Inside the dialog, we use the v-slot:activator directive to specify the button that triggers the dialog. We define a button with a plus sign icon inside the slot. By binding the @click event to dialog = true, we can open the dialog when the button is clicked.
• The v-card component contains the content of the dialog. It consists of a title, a text field for users to input the area name, and action buttons for canceling or adding the area.
• The v-card-actions component aligns the buttons to the right using v-spacer and specifies the @click events for resetting the dialog and adding the area.

Implementing Dynamic Item Dialogs

In addition to adding dialog functionality for areas, we also want to enable users to add items to each individual area. To achieve this, we’ll create a separate dialog for each area.

To get started, add the following code snippet inside the area expansion panels:

<v-btn
  v-for="instance in area.instances"
  :key="instance.id"
  @click="activateItemDialog(area)"
  color="pink"
  fab
  dark
  small
>
  <v-icon>mdi-plus</v-icon>
</v-btn>

This code generates a dynamic button for each area with the plus sign icon. By binding the @click event to the activateItemDialog method and passing in the corresponding area, we can trigger the dialog and specify which area the dialog relates to.

Handling Dialog Logic

Now, let’s implement the logic for the dialog functionality. We’ll start by defining the necessary data properties and methods.

data() {
  return {
    dialog: false,
    areaName: '',
    addItemDialog: {
      isActive: false,
      area: null,
      name: '',
    },
  };
},
methods: {
  reset() {
    this.dialog = false;
    this.areaName = '';
  },
  addArea() {
    // Logic for adding the area
  },
  activateItemDialog(area) {
    this.addItemDialog.isActive = true;
    this.addItemDialog.area = area;
    this.addItemDialog.name = '';
  },
  resetItemDialog() {
    this.addItemDialog.isActive = false;
    this.addItemDialog.area = null;
    this.addItemDialog.name = '';
  },
  addItem() {
    // Logic for adding the item to the area
  },
},

The data section defines the dialog variable, which controls the visibility of the area dialog, and the areaName variable for storing the user input.

We also introduce the addItemDialog object, which contains properties for the item dialog. The isActive property specifies whether the dialog is open or closed, the area property represents the current area in focus, and the name property stores the name of the item being added.

The reset method resets the dialog by setting the dialog variable to false and clearing the areaName field.

The addArea method handles the logic for adding the area. We’ll add the necessary logic later.

The activateItemDialog method activates the item dialog by setting the isActive property to true, and binds the corresponding area and an empty name to the addItemDialog object.

The resetItemDialog method resets the item dialog, setting the isActive property to false, and clearing the area and name fields.

Finally, we have the addItem method, which will handle the logic for adding the item to the area. We’ll implement this logic later as well.

Styling and Final Touches

To enhance the visual appeal of the buttons and align them to the right side, we can add some styling using Vuetify’s built-in classes.

.v-btn.right {
  margin-left: auto;
}

.v-btn.fab.small {
  width: 32px;
  height: 32px;
}

These CSS styles ensure that the buttons are right-aligned and have a smaller size.

With these changes, we have successfully implemented the necessary dialog components and logic for adding areas and items to our application.

FAQs

Q: How do I open the dialog to add an area or item?
A: To open the dialog, simply click the + button corresponding to the desired action. For adding areas, click the plus sign in the Add Area section. To add items to an area, click the corresponding area’s plus sign button.

Q: Can I cancel the dialog and close it without adding an area or item?
A: Yes, you can cancel the dialog by clicking the Cancel button. This will close the dialog without making any changes.

Q: What happens if I try to add an area or item with a name that already exists?
A: If you attempt to add an area or item with a name that already exists, an error message will be displayed, and the addition will be aborted. Please ensure that each name is unique to avoid conflicts.

Conclusion

In this session, we added dialog functionality to our Vue.js application to allow users to add areas and items. Through the use of Vuetify components and custom methods, we created a seamless process for enhancing user interaction and improving the user interface. With these new operations in place, our application is now more equipped to handle users’ needs.

Stay tuned for our next video, where we will be implementing API endpoints and actions for these operations, enabling us to store the data on the backend and create a more robust and complete application.
