<ul>
<li><p><strong><code>gorm.Open</code> return type <code>*gorm.DB</code> instead of <code>gorm.DB</code></strong></p>
</li>
<li><p><strong>Updating will only update changed fields</strong></p>
<p>Most applications won't be affected, only when you are changing updating values in callbacks like <code>BeforeSave</code>, <code>BeforeUpdate</code>, you should use <code>scope.SetColumn</code> then, for example:</p>
<pre><code class="lang-go"><span class="hljs-keyword">func</span> (user *User) BeforeUpdate(scope *gorm.Scope) {
<span class="hljs-keyword">if</span> pw, err := bcrypt.GenerateFromPassword(user.Password, <span class="hljs-number">0</span>); err == <span class="hljs-literal">nil</span> {
scope.SetColumn(<span class="hljs-string">"EncryptedPassword"</span>, pw)
<span class="hljs-comment">// user.EncryptedPassword = pw // doesn't work, won't including EncryptedPassword field when updating</span>
}
}
</code></pre>
</li>
<li><p><strong>Soft Delete's default querying scope will only check <code>deleted_at IS NULL</code></strong></p>
<p>Before it will check <code>deleted_at</code> less than <code>0001-01-02</code> also to exclude blank time, like:</p>
<p><code>SELECT * FROM users WHERE deleted_at IS NULL OR deleted_at <= '0001-01-02'</code></p>
<p>But it is not necessary if you are using type <code>*time.Time</code> for your model's <code>DeletedAt</code>, which has been used by <code>gorm.Model</code>, so below SQl is enough</p>
<p><code>SELECT * FROM users WHERE deleted_at IS NULL</code></p>
<p>So if you are using <code>gorm.Model</code>, then you are good, nothing need to be change, just make sure all records having blank time for <code>deleted_at</code> set to <code>NULL</code>, sample migrate script:</p>
</li>
</ul>
<pre><code class="lang-go"><span class="hljs-keyword">import</span> (
<span class="hljs-string">"github.com/jinzhu/now"</span>
)
<span class="hljs-keyword">func</span> main() {
<span class="hljs-keyword">var</span> models = []<span class="hljs-keyword">interface</span>{}{&User{}, &Image{}}
<span class="hljs-keyword">for</span> _, model := <span class="hljs-keyword">range</span> models {
db.Unscoped().Model(model).Where(<span class="hljs-string">"deleted_at < ?"</span>, now.MustParse(<span class="hljs-string">"0001-01-02"</span>)).Update(<span class="hljs-string">"deleted_at"</span>, gorm.Expr(<span class="hljs-string">"NULL"</span>))
}
}
</code></pre>
<ul>
<li><p><strong>New ToDBName logic</strong></p>
<p>Before when GORM convert Struct, Field's name to db name, only those common initialisms from <a href="https://github.com/golang/lint/blob/master/lint.go#L702" target="_blank">golint</a> like <code>HTTP</code>, <code>URI</code> are special handled.</p>
<p>So field <code>HTTP</code>'s db name will be <code>http</code> not <code>h_t_t_p</code>, but some other initialisms like <code>SKU</code> that not in golint, it's db name will be <code>s_k_u</code>, which looks ugly, this release fixed this, any upper case initialisms should be converted correctly.</p>
<p>If your applications using some upper case initialisms which doesn't exist in <a href="https://github.com/golang/lint/blob/master/lint.go#L702" target="_blank">golint</a>, you need to overwrite default column name with tag, like <code>gorm:"column:s_k_u"</code>, or alert your database's column name according to new logic</p>
</li>
<li><p>Error <code>RecordNotFound</code> has been renamed to <code>ErrRecordNotFound</code></p>
</li>
