越界问题

循环查父部门名称

    employee_department_df = pd.read_sql(employee_department_sql, conn)employee_department_df['parentid'] = employee_department_df['parentid'].fillna(0).astype('int32', errors='ignore')for index, row in employee_department_df.iterrows():department_id = row['department_id']parent_dep_id = row['parentid']dep_name = row['name']while parent_dep_id > 0:temp_df = employee_department_df.loc[employee_department_df['department_id'] == parent_dep_id]temp_dep_name = temp_df.iloc[0, 2]dep_name = temp_dep_name + '\\' + dep_nameparent_dep_id = temp_df.iloc[0, 3]detail_dep[department_id] = dep_name

日常数据都没问题，突然报了个错 IndexError: single positional indexer is out-of-bounds

然后查出来问题，客户数据表更导致的判断有问题

        while parent_dep_id > 0:

修改后的代码

    employee_department_df = pd.read_sql(employee_department_sql, conn)employee_department_df['parentid'] = employee_department_df['parentid'].fillna(0).astype('int32', errors='ignore')employee_department_df['department_id'] = employee_department_df['department_id'].fillna(0).astype('int32', errors='ignore')detail_dep = {}for index, row in employee_department_df.iterrows():department_id = row['department_id']parent_dep_id = row['parentid']dep_name = row['name']while parent_dep_id > 1:temp_df = employee_department_df.loc[employee_department_df['department_id'] == parent_dep_id]temp_dep_name = temp_df.iloc[0, 2]dep_name = temp_dep_name + '\\' + dep_nameparent_dep_id = temp_df.iloc[0, 3]detail_dep[department_id] = dep_name

最终修改判断 if len(temp_df.index) == 0

        department_id = row['department_id']parent_dep_id = row['parentid']dep_name = row['name']while parent_dep_id > 1:temp_df = employee_department_df.loc[employee_department_df['department_id'] == parent_dep_id]if len(temp_df.index) == 0:# print("------> 无上级部门 <------")breakelse:temp_dep_name = temp_df.iloc[0, 2]dep_name = temp_dep_name + '\\' + dep_nameparent_dep_id = temp_df.iloc[0, 3]detail_dep[department_id] = dep_name
