岗位不允许存在子级

Error message

岗位不允许存在子级

What it means

Thrown by validateDragOperation when dropPosition == 0 (drop inside as child) and the target department is of post/position type (DEPART_CATEGORY_POST). This JeecgBootBizTipException enforces the rule that a position node is always a leaf — it cannot have children. Posts represent individual job positions, not organizational containers.

Solutions

1. Add a frontend guard: disable 'drop inside' (position 0) for any node whose orgCategory is 'post'.
2. Verify the target department's orgCategory is correct — if it should be a department not a post, fix the data.
3. Display clear tooltips in the UI explaining that positions cannot contain children.

Example fix

// before
if (0 == dropPosition && DepartCategoryEnum.DEPART_CATEGORY_POST.getValue().equals(orgCategory)) {
    throw new JeecgBootBizTipException("岗位不允许存在子级");
}

// after — frontend prevents drop-inside on post nodes
function allowDropInside(dragNode, dropNode) {
    if (dropNode.orgCategory === 'post') {
        return false; // post nodes are always leaf
    }
    return true;
}

// Frontend: prevent drop-inside on post-type nodes
const isPost = (node) => node.orgCategory === DepartCategoryEnum.POST;
if (dropPosition === 0 && isPost(dropNode)) {
    ElMessage.warning('岗位不允许存在子级');
    return;
}

public boolean canDropInside(String targetOrgCategory) {
    return !DepartCategoryEnum.DEPART_CATEGORY_POST.getValue().equals(targetOrgCategory);
}

try {
    service.updateChangeDepart(changeDepartVo);
} catch (JeecgBootBizTipException e) {
    if (e.getMessage().contains("岗位不允许存在子级")) {
        return Result.error("岗位节点不能包含子部门");
    }
    throw e;
}

When it happens

Trigger: Dropping a department or node inside a post-type department (dropPosition=0), attempting to make it a child of a position. The switch condition catches (0 == dropPosition && POST type).

Common situations: User tries to nest departments under a position node; tree UI allows drop-inside on all nodes regardless of type; org structure was set up with positions where departments were intended.
