I am doing a Python Flask project, trying to "edit" a current "object" from postgresql via FlaskForm. So far, I have managed to retrieve the values of the "recipe" object using value for but I need to manually render recipe.description.

However, how do I go about the same using the input[file] to retrieve recipe.picture ?

Here is my form.html

<form method="POST" action=" url_for('recipes.edit_recipe', recipe_id=recipe.id) " enctype="multipart/form-data">
 form.csrf_token 
 form.hidden_tag() 
 <fieldset class="form-group">
 <div class="modal-body">
 % for field in form if field.name != "csrf_token" %
 % if field.name != "btn" %
 <div class="form-group">
 field.label(class="form-control-label form-control-lg") 
 <!-- if fiend.something == title, need to insert title -->
 % if field.name == "picture" %
 field(class="form-control", value=recipe.picture) 
 <figure>
 <img src="recipe.picture" class="small-preview" alt="preview">
 <figcaption>Current photo</figcaption>
 </figure>
 % endif %
 % if field.name == "title" %
 field(class="form-control", value=recipe.title) 
 % endif %
 % if field.name == "description" %
 <textarea class="form-control" name="description" id="description" cols="30" rows="5"> recipe.description </textarea>
 % endif %
 <!-- end the if block -->
 % for error in field.errors %
 error 
 % endfor %
 </div>
 % else %
 <div class="modal-footer">
 <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
 form.btn(class="btn btn-info") 
 </div>
 % endif %
 % endfor %
 </div>
 </fieldset>
 </form>

Here is my views.py

@recipes_blueprint.route('/<int:recipe_id>', methods=['POST'])
@login_required
def edit_recipe(recipe_id):
 form = UpdateRecipeForm()
 that_recipe = Recipe.get_or_none(Recipe.id == recipe_id)
 recipe_owner = User.get_or_none(User.id == that_recipe.user_id)
 if form.validate_on_submit():
 if recipe_owner != current_user:
 flash("Only owner of the recipe can amend the details", "danger")
 return redirect(url_for('recipes.read_recipe', recipe_id=recipe_id))
 else:
 if "picture" not in request.files:
 flash("No picture key in request.files", 'danger')
 return redirect(url_for('recipes.read_recipe', recipe_id=recipe_id))
 file = request.files['picture']
 if file.filename == '':
 flash("Please select a file", 'danger')
 return redirect(url_for('users.update_user'))
 if file and allowed_file(file.filename):
 file.filename = secure_filename(file.filename)
 output = upload_file_to_s3(file, app.config['S3_BUCKET'])
 updated_recipe = Recipe.update(
 title=form.data['title'],
 description=form.data['description'],
 picture=output
 ).where(Recipe.user_id == recipe_owner.id)
 updated_recipe.execute()
 flash("Recipe updated successfully", "success")
 return redirect(url_for('recipes.read_recipe', recipe_id=recipe_id))
 return render_template('read_that_recipe.html', recipe=that_recipe, form=form)
