Recently, in the process of using the operation and maintenance platform, when I found that the submitted SQL statement contains an expression, part of the data will be lost when it is stored in the database. For example, the original sentence is "update a set c='aaa emoji expression \n\n ~emoji expression" \n\n'", it becomes "update a set c='aaa emoji" after being stored in the library. Later, this problem was solved using the utf8mb4 character set. Django uses the utf8mb4 character set and performs the following configuration:
The database configuration is as follows:
[client] default-character-set = utf8mb4 [mysql] default-character-set = utf8mb4 [mysqld] character-set-client-handshake = FALSE character-set-server = utf8mb4 collation-server = utf8mb4_unicode_ci
2.django configuration
DATABASES = {
'default': {
...
'OPTIONS': {'charset':'utf8mb4'},
},
}
