كيفية إضافة حقول مخصصة إلى النماذج

angus · 31 أكتوبر 2024، 11:49ص

لقد قمت بتحديث دليل حقول الموضوع المخصصة لـ Discourse 3.4.0. سأقوم بتحديث دليل الفئة الأسبوع المقبل.

pipkin · 8 أبريل 2025، 10:10ص

أهلاً @angus، شكراً لك على إضافة category-custom-fields!\n\nمع ذلك، لا يتم تخزين القيم عند النقر على \u003ckbd\u003eحفظ الفئة\u003c/kbd\u003e:\n\n- مربع الاختيار من مثالك غير المعدل يعود فوراً إلى غير محدد.\n- الحقل المخصص لا يتم تخزينه في قاعدة البيانات (لقد راقبت هذا).\n\n

\n\nلا أحصل على أي أخطاء.\n\nهل يمكنك مساعدتي في معرفة السبب؟ لا أستطيع العثور على أي أسباب.

SubStrider · 2 يونيو 2025، 9:02ص

هل هناك طريقة لضمان أن تكون الحقول المخصصة إلزامية من جانب الخادم؟

pfaffman · 2 يونيو 2025، 9:47ص

في المعتاد، ستستخدم نموذج ModelCustomField لإضافة بياناتك الخاصة في المكوّن الإضافي.

هل يمكنك توضيح ما الذي تحاول فعله؟

SubStrider · 2 يونيو 2025، 9:56ص

لقد أضفت الحقول المخصصة وأنا قادر على حفظها في قاعدة البيانات في جدول مخصص. ومع ذلك ، أريد أن أجعل هذه الحقول المخصصة إلزامية على كل من جانب العميل وجانب الخادم. على جانب العميل لا يزال الأمر سهلاً نسبيًا. على جانب الخادم ، هل هناك طريقة قياسية للتحقق من أن جميع الحقول المخصصة قد تم ملؤها ثم السماح بإنشاء الموضوع فقط. الآن حتى إذا كانت الحقول المخصصة فارغة ، فسيتم إنشاء الموضوع بدونها.

pfaffman · 2 يونيو 2025، 10:06ص

آه. هذا سهل، لكنني لست جيدًا بما يكفي في Rails لأخبرك كيف. ولكن سيكون لديك الكود الخاص بك خلف رد اتصال (Active Record Callbacks — Ruby on Rails Guides) يتم استدعاؤه قبل الإنشاء وسيفشل إذا لم تكن الحقول الخاصة بك موجودة.

Hi everyone,

I set up a plugin based on Topic Custom Fields and everything was working fine until I updated Discourse to version 3.6.0.beta1-dev.

Topic list => OK, the columns appear correctly in the listing
Topic title => OK, the columns appear correctly under the topic title
Topic composer => KO, the fields don’t appear and I can’t compose and validate the message.

Here is the message encountered:

Are any of you experiencing the same problem?

jahan_gagan · 30 سبتمبر 2025، 8:37ص

مرحباً @cdervout ،

المشكلة
استخدم مكون إدخال حقل الموضوع المخصص الصيغة القديمة:

{{on "change" (action @onChangeField value="target.value")}}

صيغة (action …) هذه غير مدعومة في مكونات Glimmer الحديثة.
ونتيجة لذلك، لم يتم عرض الحقل على الإطلاق في المنشئ.

الإصلاح
تم استبدال الصيغة القديمة بإجراء Glimmer حديث:

{{on "input" this.handleInputChange}}

وتمت إضافة الدالة JS المقابلة:

@action
handleInputChange(event) {
  this.args.onChangeField(event.target.value);
}

يضمن هذا عرض الحقل بشكل صحيح في المنشئ.

كود المكون المعاد هيكلته

تعديل: لقد قمت بإنشاء طلب سحب (PR) لنفس الشيء

cdervout · 30 سبتمبر 2025، 1:30م

شكراً، كل شيء يعمل بشكل جيد! لقد قمت بتكييف الكود في حالة ما إذا كان الحقل عبارة عن مربع اختيار. لاسترداد القيمة، كان عليّ استخدام event.target.checked بدلاً من event.target.value
