What should I do if cubes reports an error ConfigurationError(\"Store \'%s\' has no type specified\" % name)

The reason for the error

"ConfigurationError('Store '%s' has no type specified' % name)" This error is This is caused by not specifying the storage type when using cubes framework of python. The cubes framework needs to specify the type of data storage in the configuration file. If it is not specified, this error will occur.

How to solve

The type of data storage should be specified in the configuration file of the cubes framework.

Specifically, you need to specify the storage type in the "store" section of the configuration file.

For example:

"store": {
"type": "sql",
"url": "sqlite:///data.sqlite"
}

Here we specify the storage type as "sql" and specify the URL where the data is stored.

Alternatively, you can use other types of storage, such as "monGo" or "Redis".

In addition, sometimes it is necessary to set other parameters in the configuration file and configure them according to different storage types.

In short, make sure there is a legal "store" configuration in the configuration file and the data storage type can be correctly specified to solve this problem.

Usage example

Indeed, here is an example of using SQLite as a data storage:

{
"metadata": {
"cubes_version": "1.0",
"cube": "sales"
},
"model": {
"dimensions": [
{
"name": "date",
"levels": [
{
"name": "year",
"attributes": [
"year"
]
},
{
"name": "month",
"attributes": [
"month"
]
},
{
"name": "day",
"attributes": [
"day"
]
}
]
},
{
"name": "product",
"levels": [
{
"name": "product",
"attributes": [
"product_name",
"product_code"
]
}
]
}
],
"measures": [
{
"name": "amount",
"aggregations": [
"sum"
]
}
]
},
"store": {
"type": "sql",
"url": "sqlite:///data.sqlite"
}
}

The above configuration file specifies the use of "sql" type storage, and uses SQLite as the database storage, and is configured in the "store" section.

It should be noted that the value of "url" here is "sqlite:///data.sqlite", which means creating a SQLite named "data.sqlite" locally Database .

In addition, you can also use other types of storage such as mongoDB as storage. Just specify the storage type as "mongo" in the configuration file and set the relevant connection parameters.
