How to limit file size in binary field odoo-CodePudding

I have a binary field and I want to limit upload file size to less than 1MB. How can I do that.

binary_field = fields.Binary(string="Upload Image")

CodePudding user response：

The file size of binary fields is limited with max_upload_size which is set to the session max_file_upload_size or to the default value of 128 Mb, it can be changed using the system parameter web.max_file_upload_size

The max upload size is hard coded and can't be specified from a binary field

You can extend the existing binary field and set the max file size based on a field attribute.

Example:

/** @odoo-module */

import fieldRegistry from 'web.field_registry';
import basicFields from 'web.basic_fields';
import session from 'web.session';


var CustomFieldBinaryFile = basicFields.FieldBinaryFile.extend({
    init: function (parent, name, record) {
        this._super.apply(this, arguments);
        if(this.attrs.max_upload_size) {
            this.max_upload_size = this.attrs.max_upload_size;
        }
    },
});

var CustomFieldBinaryImage = basicFields.FieldBinaryImage.extend({
    init: function (parent, name, record) {
        this._super.apply(this, arguments);
        if(this.attrs.max_upload_size) {
            this.max_upload_size = this.attrs.max_upload_size;
        }
    },
});

fieldRegistry.add('custom_binary', CustomFieldBinaryFile);
fieldRegistry.add('custom_binary_image', CustomFieldBinaryImage);

Add the js file to the assets entry in the manifest file under web.assets_backend

To use it set the following attributes on the binary field tag: widget and max_upload_size

Example:

<field name="binary_field" widget='custom_binary' max_upload_size="1048576"/>
