Dhibaatada ugu weyn ayaa ah in svgs aysan taageerin goobta sawirka caadiga ah ee Django. Waxaad u baahan tahay inaad isticmaasho fasalka goobta gaarka ah si aad u kaydiso svgs.
?
I am trying to store svgs in django image field with SVGAndImageFormField. I have tried this:
<code>class SVGAndImageFormField(forms.ImageField):
def to_python(self, data):
f = super().to_python(data)
if isinstance(f, FileObject):
return f
if hasattr(data, 'read'):
return data
if not data: # empty file upload field returns None instead of '' like the rest of the fields. get around it.
return ''
try: # handle when it's just a path instead of a file object. (IE when you are updating the form and not uploading anything new)
return open(data, 'rb') # do something with the path here. probably save it off.
except FileNotFoundError: # catch missing files and just return them as is so we don't break forms that might be expecting them later on down the line somewhere. (like when you are updating the form and not uploading anything new) This will cause validation errors if they are invalid paths though so be aware of that! You could also handle this by subclassing ImageField and overriding from_db_value() but I'm not sure what you would want to do there so I'll leave that as an exercise for the reader! 😉 https://docs.djangoproject.com/en/2.0/ref/models/fields/#django.db.models.fields.files._ImageFieldFile https://docs.djangoproject.com/en/2.0/ref/models/fields/#field-types https://docs-archive-old-1x1x1x1x1x4x3xx11111l1111111111111l22222222d11111111l3ooooooooxxxxxxxxxxxxxxxxxxxxxxxxxxxxdddddddddddddxxxxxxxeeeeeeeeeeeeeeexxxxxxxxxxxxxxxxfoooooooooooooooxxxxxxxxxxxxxxxgpppppppppppppppqrrrrrrrrrrrrrrrsssssssssssssstttttttttuuuuuuuuvvvvvvvvwwwwwwwwyyyyyyzzzzzzz{{{{{{|}}}}}}}~€€€€‚ƒ„…†‡ˆ‰Š‹ŒŽ‘’"•–—˜™š›œžŸ ¡¢£¤¥¦©«®°²¶·»½ÀÂÄÇÉÊËÎÏÔ×Ûßàâäçéêëîïôûüˆˇˉ–––––—―™š›œ–—˜™š›œ"•–—˜™š•–—˜™š•–—˜™š•–—˜™š•–—˜™š• – — – — – — – — – — – — – — – — – — ¢£¤ ¥ ¦ © « ® ° ² ¶ · » ½ À â Ä ç é êëîïôûüˆˇˉ––––––—" • - - - - - " • - - - " • -- -- -- -- " • -- -- " • --- --- --- --- " • --- --- " • ---- ---- ---- ---- ---- ---- ---- ---- ----- ------ -------- --------- ---------- ------------------- ------------------------------------------------------------ ----------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------</code>
Kani waa ImageField caado ah oo kuu ogolaanaya inaad geliso mid sawir ama SVG ah.
Habka to_python wuxuu ka qaadaa xogta foomka oo u beddelaa FileObject.
Haddii xogtu ay horeba u ahayd FileObject, way soo celinaysaa.
Haddi xogtu leedahay sifada akhriska (tusaale ahaan haddii ay tahay shay faylka u eg), way soo celisaa.
Haddii xogtu ay madhan tahay (”), way soo noqotaa” (tani waa sababta oo ah meelaha fayl-galka ah ee maran midna ma soo celiyo halkii ay ahayd “, sida meelaha kale).
Haddii xogtu aysan madhnayn, waxay isku daydaa inay u furto fayl ahaan (adoo adeegsanaysa qaabka 'rb'). Haddii ay tani ku guulaysato, waxay soo celinaysaa shayga faylka. Haddaysan ahayn, waxay soo celinaysaa xogta lafteeda (tani waa si foomamka laga yaabo inay filayaan xogtan hadhow ha jabin).
Oggolow in faylasha SVG lagu dhejiyo ImageField iyada oo loo sii marayo maamulka Django
Haddii aad rabto inaad u oggolaato faylasha SVG in lagu dhejiyo ImageField ee Django, waxaad sidaas samayn kartaa adigoo ku daraya xariiqda soo socota faylkaaga settings.py:
IMAGE_FIELD_MAX_FILE_SIZE = 1000000
Sida loo kaydiyo Svgs gudaha goobta sawirka Django
Waxaa jira dhowr siyaabood oo kala duwan oo lagu kaydiyo svgs gudaha Django. Habka ugu fudud waa in la isticmaalo fasalka ImageField. Fasalkani wuxuu kuu ogolaanayaa inaad qeexdo URL ama marin-u-helka sida qiimaha goobta.
Hab kale oo lagu kaydiyo svgs ee Django waa in la isticmaalo fasalka ImageGallery. Fasalkani wuxuu kuu ogolaanayaa inaad u qeexdo URL ama filepath inay yihiin qiimaha goobta, waxayna si toos ah u soo saari doontaa sawiro sawiro ah oo ku salaysan jidkaas.
