我也是遇到了一樣的問題在內(nèi)容顯示判斷里面加個(gè)判斷是否是最后一篇文章再對(duì)內(nèi)容進(jìn)行查詢

if?article.article_id?==?article_id:

????if?next_index?==?len(all_article):
????????previous_article?=?all_article[(previous_index-1)]
????????next_article?=?all_article[next_index-1]

????else:
????????previous_article?=?all_article[previous_index]
????????next_article?=?all_article[next_index]

????curr_article?=?article
????break

你是views.py文件里估計(jì)寫的有點(diǎn)問題？

for?index,?article?in?enumerate(all_article):
????if?index?==?0:
????????previous_index?=?index
????????next_index?=?index?+?1

????else:
????????previous_index?=?index?-?1
????????next_index?=?index?+?1

????if?article.article_id?==?article_id:
????????curr_article?=?article
????????previous_article?=?all_article[previous_index]
????????next_article?=?all_article[next_index]
????????break

看我這里加粗的部分！
