The provided Vue component template has several improvements and corrections:

1. Attribute Errors: Fixed attrs syntax issues, such as using { label-width='xx' }.
2. Relation Field Settings:
   • Updated relation_trigger_field_dict to correctly reference trigger_value when calling the request URL.
   • Removed duplicate children arrays that were causing confusion and added missing ones where necessary.
3. Option List Correctness:
   • The option list for each select control is consistent with other fields.
4. Text Field Name Handling:
   • Added missing text_field, value_field, required_asterisk, and setting correct labels for multi-level structure.

Suggested Changes:

1. Updated HTML Attributes:

     :props-info="{ tabs_label: '用户', active-name: 'first-tab', tab-content-class:'content-card'" />
     style="width:100%"
   </el-form>

2. Fixed Relation Trigger Field Dictionary Keys:
   Use field instead of key (as used in option_lists).

3. Consistent Option Lists:
   Ensure every input field's options match its configuration in both input_type specific properties and general attributes (placeholder, custom settings) if applicable.

Here’s an optimized version based on these suggestions:

  <dynamic-form
    :model="form_data"
    :render-data="damo_data"
    ref="dynamicsFormRef"
    :other-params="{ current_workspace_id: '{{ current_workspace_id }}' }" // Update dynamic parameters here.

This revised format adheres to standard practices and improves maintainability while addressing the identified issues.

Code Check and Suggestions

Regularities:

1. Duplicate Imports: Multiple imports of functions like ref, onBeforeMount, watch, etc., should be consolidated.
2. Unused Variables: The variable load is declared but not used anywhere.
3. Redundant Import in get_formDefaultValues (_: lodash package).
4. Unnecessary Parameter Passing in trigger Function (template_field, triger_value, setting, and self).

Potential Issues:

1. String Manipulation Using replace Method: This could lead to unexpected behavior with regex, especially if \u00A0 (non-breaking space) is encountered.

Optimization Suggestion:

1. Combine Repeated Logic: For example, handle form value mapping logic more cleanly across multiple functions.
2. Avoid Unnecessary Object Creation: Reduce the creation of unnecessary objects, such as empty/default values.

This version addresses many of the issues and optimizations identified earlier, making the code clearer, more maintainable, and secure.

[shaohuzhang1]

Your code structure looks mostly sound, but there are a few areas that could be improved:

1. Code Duplication: The open method is called twice with similar logic when checking for existing data in props.modelValue. This can be consolidated.

2. Null/Undefined Handling: In the show function, you handle empty arrays (values && values.length > 0) incorrectly. It's better to explicitly check if the array contains elements.

3. Tooltip Styling: The tooltip should have an auto-width setting so it doesn't exceed its container width automatically or manually set a specific maximum width.

4. Dynamic Component Import: Ensure that '@/components/dynamics-form/index.vue' is correctly importing without errors.

Here’s a revised version of your script part addressing these concerns:

<script setup lang="ts">
import DynamicsForm from '@/components/dynamics-form/index.vue'
import { ref, onMounted } from 'vue'
import { cloneDeep, get, isArray } from 'lodash'

const props = defineProps<{
  label: any,
  modelValue?: any,
  formValue: any,
  view?: boolean
}>()

defineEmits(['update:modelValue'])

// Initialize refs and variables
const dialogVisible = ref(false)
const dynamicsFormRef = ref<InstanceType<typeof DynamicsForm>>()
let form_data = ref<{ [key: string]: any } | undefined>()

// On component mount, initialize form data
onMounted(() => {
  updateFormData();
})

const open = () => {
  updateFormData() // Update form data if necessary before opening the dialog
  dialogVisible.value = true;
}

const close = () => {
  dialogVisible.value = false
  form_data.value = undefined
}

/**
 * Get updated form data either from props or current form state
 */
const updateFormData = () => {
  if (!form_data.value && props.modelValue) {
    form_data.value = cloneDeep(props.modelValue);
  }
}

const show = (field: any): boolean => {
  if (field.relation_show_field_dict) {
    const keys = Object.keys(field.relation_show_field_dict);
    
    for (const key of keys) {
      let value = get(props.formValue, key);
      
      if (isArray(value) && value.length > 0) {
        const values = field.relation_show_field_dict[key];
        
        if (values.some(val => val === value)) {
          return true; // Value found in relation show fields list
        }
      }

      return !value || value === null; // No value or null means always visible
    }
  }

  return true;
};

const submit = async () => {
  try {
    await dynamicsFormRef.value!.validate(); // Await validation to ensure complete input
    dialogVisible.value = false;
    emit('update:modelValue', form_data.value!);
    form_data.value = undefined;
  } catch (error) {
    console.error("Validation failed", error); // Handle validation errors
  }
};
</script>
