查询所有课程列表
逻辑就是返回所有课程,也很简单,直接上代码
def get_all_courses(db: Session):
"""查询所有课程列表"""
try:
all_courses = get_all(db)
to_client = []
if all_courses:
for _ in all_courses:
course_detail = CourseDetail(
id=_.id,
name=_.name,
icon=_.icon,
desc=_.desc,
catalog=_.catalog,
onsale=_.onsale,
owner=get_by_uid(db, _.owner).username,
like_num=_.like_num
)
to_client.append(course_detail.dict())
except:
logger.warning(f"查询失败:{traceback.format_exc()}")
return response(code=101701, message="查询失败")
return response(data=to_client)
接口api
@course_router.get("/student_course/all", summary="查询所有课程")
def get_all(db: Session = Depends(create_db)):
return get_all_courses(db)

查询学生自己的课程列表
逻辑也比较简单
def db_student_like(db: Session, user_id: int):
"""学生加入的所有课程"""
return db.query(StudentCourse).filter(StudentCourse.student == user_id, StudentCourse.status == False).all()
def get_student_like(user: UsernameRole, db: Session):
"""查询学生加入的所有课程"""
if user.role == "老师":
return response(code=101701, message="只有学生可以查看自己加入的课程列表")
try:
db_user = get_by_username(db, user.username)
student_likes = db_student_like(db, db_user.id)
to_client = []
if student_likes:
for _ in student_likes:
db_course = get_course_by_id(db, _.course)
course_detail = CourseDetail(
id=db_course.id,
name=db_course.name,
icon=db_course.icon,
desc=db_course.desc,
catalog=db_course.catalog,
onsale=db_course.onsale,
owner=get_by_uid(db, db_course.owner).username,
like_num=db_course.like_num
)
to_client.append(course_detail.dict())
except:
logger.warning(f"method get_student_like error: {traceback.format_exc()}")
return response(code=101702, message="查询失败")
return response(data=to_client)
接口api
@course_router.get("/student_course", summary="查询学生加入的所有课程")
def get_student_like_course(user: UsernameRole = Depends(get_current_user), db: Session = Depends(create_db)):
return get_student_like(user, db)
测试
以上就是查询所有课程以及学生加入的课程接口
