I have a FileField field in a Django model that I want to read to display in my ReportBro report that use AWS S3 Bucket.
class Inspection_File(models.Model): inspection = models.ForeignKey(Inspection, null=True, on_delete=models.CASCADE, related_name='fk_inspection_inspectionfile') imageNumber = models.IntegerField(null=True, blank=True) file_name = models.CharField(max_length=500, null=True, blank=True) file = models.FileField(max_length=500, storage=InspectionDataStorage(), null=True, blank=True) thumbnail = models.CharField(max_length=500, null=True, blank=True) category = models.ForeignKey(Inspection_File_Category, null=True, on_delete=models.CASCADE, related_name='fk_inspfilecategory_inspectionfile') commentary = models.TextField(blank=True, null=True) class Meta: db_table = 'ins\".\"file'
ReportBro has 3 ways to print images, open a local file, by base64, or by URL images_reportbro. However, in my case, using the URL is a very long process, so I need to read the file to keep it in memory and send it directly to the report. Try using this code:
test = image.file.open(mode='rb')
It has not worked, the report does not give me an error but the spaces appear blank, as if it did not recognize the type of file that I am sending. But when I open a file from my directory it works. When reviewing the data types I realized that locally I have an io.BufferedReader and in the other a FileField Class.
marker_image = open('media/db model.png', 'rb') # <class '_io.BufferedReader'> test = image.file.open(mode='rb') # <class 'django.db.models.fields.files.FieldFile'>
In theory, that would be the main problem why it doesn’t work, does anyone know if a FileField can be transformed into a BufferedReader?
