Macro diesel::infer_schema
[−]
[src]
macro_rules! infer_schema { ($database_url: expr) => { ... }; ($database_url: expr, $schema_name: expr) => { ... }; }
Queries the database for the names of all tables, and calls
infer_table_from_schema!
for each
one. A schema name can optionally be passed to load from schemas other than
the default. If a schema name is given, the inferred tables will be wrapped
in a module with the same name.
Attempting to use the env!
or dotenv!
macros here will not work due to
limitations of the Macros 1.1 system, but you can pass a string in the form
"env:SOME_ENV_VAR"
or "dotenv:SOME_ENV_VAR"
to achieve the same effect.
This macro can only be used in combination with the diesel_codegen
crate.
It will not work on its own.
If any column name would collide with a rust keyword, a _
will
automatically be placed at the end of the name. For example, a column called
type
will be referenced as type_
in the generated module.
