我想在我的網(wǎng)頁頁腳部分編輯我的聯(lián)系人，我做了這個：在我的管理頁面我做了它所以我可以填寫一個表格，每個聯(lián)系人有 4 個輸入form.contact1 form.contact2 form.contact3 form.contact4......同時(shí)我制作了一個Contacts模型包含content柱子。我的路線代碼：@app.route('/admin/media-kontaktai', methods=['GET', 'POST'])@login_requireddef media_contacts(): form = MediaContactsForm() if form.validate_on_submit(): rows = db.session.query(func.count(Contacts.id)).scalar() for x in range(1, rows+1): erace_contact = Contacts.query.get(x) db.session.delete(erace_contact) db.session.commit() if form.contact1.data: contact = Contacts(content=form.contact1.data) db.session.add(contact) db.session.commit() if form.contact2.data: contact = Contacts(content=form.contact2.data) db.session.add(contact) db.session.commit() if form.contact3.data: contact = Contacts(content=form.contact3.data) db.session.add(contact) db.session.commit() if form.contact4.data: contact = Contacts(content=form.contact4.data) db.session.add(contact) db.session.commit() flash('Informacija atnaujinta!', 'success') return redirect(url_for('media_contacts')) elif request.method == 'GET': contact1 = Contacts.query.get(1) form.contact1.data = contact1.content contact2 = Contacts.query.get(2) form.contact2.data = contact2.content contact3 = Contacts.query.get(3) form.contact3.data = contact3.content contact4 = Contacts.query.get(4) form.contact4.data = contact4.content contacts = Contacts.query.all() return render_template('a-media-kontaktai.html', title='Media ir kontaktai', form=form, contacts=contacts)

這是未經(jīng)測試的?？纯此欠裼行В?/p>
for i in range (1,5):
if form['contact' + str(i)].data:
contact = Contacts(content=form['contact' + str(i)].data)
db.session.add(contact)
db.session.commit()

我還沒有測試過這個，但它應(yīng)該可以工作，或者至少讓你走上正確的道路，了解如何進(jìn)一步壓縮它。
