Data Input and Modification
Explore data input and modification with Momen for efficient database management. Our comprehensive guide covers all methods with detailed explanations.
Before reading this article, it is recommended to familiarize yourself with Data Retrieval and Display.
Preconditions for Input and Modifying
Where to Input the Data
Inputting and modifying operations are essentially performed on the data tables where the data is stored. Therefore, before inputting or modifying, you must have already created the corresponding data tables.
Sources of Data for Writing
The content input from text boxes, images, or videos selected and uploaded from a gallery, files uploaded from the desktop (including audio, PDF, Word files, etc.), all these inputs or uploads can be written into the database.
How to Obtain the Data to Input in Momen
Using Input/Selection Components to Get the Data
As shown in the figure below, you can obtain the necessary data to input by using components such as【Text Input】,【Switch】,【Image Picker】,【Video Picker】,【Select View】,etc., for inputing, selecting, and uploading.
Locating Data for Input, Selection, and Upload
To perform an input operation, you can find this data by clicking on the【+】sign and selecting the【Input】.
Renaming Components During Data Inputting:
In many pages, you may encounter multiple input/selection components, leading to multiple selectable component names when choosing the data to input.
For example, there might be input box components for customer names and contact phone numbers on a page. These components, if not renamed, might be called【Text Input 1】,【Text Input 2】, making it difficult to quickly and accurately identify which one is for retrieving the customer's name. Therefore, renaming components is essential.
Standard Naming Convention: Content_Component Type
For instance, the default name for the【Text Input】component is【Text Input】.If this component is meant to gather the user's name, it is recommended to change the component's name to【Customer Name_Text Input】. As demonstrated in the video above, this naming convention will allow you to accurately retrieve the corresponding data when selecting the input box data to input.
Method to Rename Components:
Select the component you wish to rename, find【Component Name】at the top of the right sidebar, and double-click the component name to modify it directly.
Inputs
Definition: The so-called input operation refers to the process of adding one or more pieces of data to a database.
The following common actions are examples of input operations:
Posting Content: input on social media, tweeting, sending a WeChat message to a friend, recording a to-do in an app, organizing an event, making an event reservation, all involve input data to a specific database.
Purchasing Products: Adding items to a shopping cart, successful product purchases, placing an order for delivery, and adding a new shipping address are all examples of data input operations.
Interactions such as Bookmarking, Liking, Commenting, and Replying: These are also considered input operations.
Operation Methods in Momen
In Momen, operations are generally triggered by clicking or other successful actions. The input operation is typically implemented by configuring the component's action to【Request | Mutation】.
As shown in the diagram, the【Mutation - Update New】action is configured for the confirm button. In this behavior, the corresponding data column is bound to the content obtained from the【Input Box】,【Current User Data】, etc. When the confirm button is clicked, the input operation is triggered, saving the obtained data to the database.
Content That Can Be Written:
Tips:
Linked Data: This can only be chosen for input content after it has been added to the page.
In-page Data: This can only be chosen for input content after it has been added to the page.
Inputs: This option is available for input content only after input/select-type components have been added to the page.
Result Data: This can only be chosen for input content after the input/update operation has been successfully executed.
For detailed explanations and applications of the above data, please refer to the【Data Specialization】section.
Modification
The actions of updating and deleting data can collectively be referred to as modification operations.
Update
Definition: An update refers to the alteration of existing data within a data table.
The following common actions are examples of update operations:
Updating Personal Information: Changing a profile picture, username, phone number, shipping address, password, etc. This involves altering existing data within the data table to new data, and such an operation is called an update.
Updating Consumption Records: After using a credit card, credit card points may increase or decrease. This alteration to existing points data is also considered an update.
Delete
There are two types of deletion:
True Deletion Definition: This involves completely removing existing data from a database. Once a true deletion operation is executed, that data will no longer exist within the database.
False Deletion Definition: This means only modifying the status of the data, making it no longer visible or functional, but the data itself remains within the database. Example: In a scenario where the product home page displays all products,【unlisted】or【delisted】products are not shown. To achieve this effect, products that are unlisted or delisted are not removed; instead, a【status】such as【live】,【unlisted】, or【delisted】is added to the product data. Only products with a【live】status are displayed on the home page.
The following common actions are examples of delete operations:
Deleting Order Records
Removing Items from the Shopping Cart
Unfollowing, Unliking
Canceling a Reservation for an Event
Tips:
During data operations, to prevent accidental【true】deletion, which could lead to irreversible consequences, it is generally recommended to perform a【false】deletion to achieve the effect of deleting data. This method maintains the data within the system while removing its functionality or visibility.
Modification Operation Methods in Momen
In Momen, modification operations, including updates and deletions, are generally triggered by clicking.
Updating Data
As illustrated in the diagram, the 【Mutation - Update】 action is configured for the update button. Within this action, the corresponding data column is bound to the content to be updated. When the confirm button is clicked, the update operation is triggered.
It's important to note that when updating data, you must include a filter condition to specify which piece of data is to be updated; otherwise, all data will be updated.
Deleting Data
As shown in the diagram, the 【Mutation- Delete 】 action is configured for the delete button. This action requires a default filter condition to specify which piece of data is to be deleted. If no filter condition is selected and the delete button is clicked, all data from the selected table will be deleted!
Batch Mutatiomn
Definition: The operation of inputing or modifying multiple records in one or more data tables simultaneously.The following common actions are all considered bulk modification operations:
Selecting multiple images for posting when sharing on social media.
Selecting multiple products for checkout in the shopping cart, thereby generating a single order.
Selecting multiple options simultaneously for insertion into a data table after a multi-select operation.
Momen 's Methods for Bulk Operations
Inserting Multiple Records into a Table
Momen generally triggers input operations through clicking. To input multiple records, follow these steps:
After configuring the【Mutation - Insert】action, open the "Bulk Modify" mode and choose the data source for bulk writing.
Click on the data source, and select the required data fields to map (these could be specific field values within a data record).
Bind the parameters for bulk insert, with data sourced from the data binding operation by clicking on the settings next to the parameter name. Clicking the【Switch】button will complete the operation to store multiple records into a table.
Updating/Deleting Multiple Records in a Table
Momen's update/delete action is essentially a bulk operation. If you configure a filter condition during the【Mutation - Update/Delete】process, all the data that meets those conditions will be updated or deleted.
For example, in the image below, if you configure the action to update/delete hobbies, all hobby data belonging to the current user will be updated or deleted.
Input or Modifying Multiple Tables Simultaneously
In Momen, the simultaneous operation on multiple data tables is referred to as 【Batch Mutation】. You can find it within the action configuration, and add multiple input or modify actions to simultaneously input or modify multiple tables.
Concept and Application of Result Data
Definition of Result Data: After executing input or update operations, the newly written or updated data is referred to as【result data】.
Application: When configuring input or update operations, after successful execution, you can obtain the newly written or updated data through【result data】(including the data's ID and all other field contents). This information can be used for further actions.
