Nola hobetu zure COREBlog bloga III: Kolaboratzaileei gure blogean artikuluak idazteko aukera eman

COREBlog-ekin egindako blogek (eibar.org-en daudenak adibidez) ez daukate artikuluak gehitzeko pantailarik, ez bada kudeatzailearen pasahitzarekin kudeatze-pantailetan sartuta. Eta gure blogean hainbat kolaboratzaileri artikuluak idazteko aukera eman nahi badiegu, ez dugu kudeatzaile baimenak eman beste aukerarik. Baina hau kolaboratzaile batentzat konplikatuegia izan daiteke eta gure blogarentzat arriskutsua. Ikusi hemen nola egin dezakegun artikuluak idazteko pantaila bat, argazkiak gehitzeko aukera eta guzti, eta nola eman baimenak horretarako soilik.

Hasteko, blogaren erroan DTMLMethod bat sortu, "addEntryForm" izenarekin, eta eduki honekin:

<dtml-var blog_header>
<dtml-var blog_banner>
<div id="content">
<div class="blog">

Gero "objecttype" izeneko python script bat gehitu behar da, "object" izeneko parametroa hartzen duena eta eduki hau duena:

if object is None:
    return 'None'
s = str(object)
if object==s:
    return 'string'
try:
    t = object.meta_type
    return t
except:
    pass
try:
    l = len(object)
    if s[0]=='[':
        return 'list'
    if s[0]=='(':
        return 'tuple'
    if s[0]=='{':
        return 'dict'
    return 'sequence'
except:
    pass
try:
    t = object.timeTime()
    return 'DateTime'
except:
    pass
try:
    val = int(object)
    if val is object:
        return 'integer'
    return 'number'
except:
    return 'unknown'

Bukatzeko, baimen batzuk aldatu behar dira. "Manager" eta "owner" erabiltzaileei "View" baimena emango diegu hasieran aipatutako "addEntryForm" formularioan, eta "Add COREBlog entries" eta "Add documents, images and files" COREBlog objektuan.

Eta kitto! Orain kolaboratzaile berri bati artikuluak gehitzeko aukera eman nahi diogun bakoitzean, "acl_users" karpetan erabiltzaile berri bat gehituko dugu, "owner" motakoa. Hauek beren pasahitzarekin "addEntryForm" formularioa erabil dezakete artikuluak gehitzeko, hasieran irudi bat ere sartzeko aukerarekin, baina ezin dituzte kudeaketako beste pantailak ikusi.

Bi limitazio ditu oraingoz: gehitutako artikuluak testu egituratua formatuan egon behar dira eta ezin da EPOZ edizio zerbitzua erabili.
